Need help revising, and recommendation for a conclusion.

Throughout this paper is my understanding of what I have learned in class chapters 1-4, expressing my understanding and opinions. Economics is the study of how we deal with scarce resources. Microeconomics specially deals with business in the home country exclusively. This type of economics affects small businesses in the home country only. On the other hand, macroeconomics concerns our national welfare concerning trade and international business.

I believe that many things affect our economy on a microeconomics level. Things such as our understanding of our country in reflection to the world are very important. That is why we study ourselves before we study the macroeconomic principle of the world. Understanding ourselves is what microeconomics teaches us. Working from the inside out. The world is a place where there are differences in our wants and what we get. That is what makes items scarce. That is what positive economics is. Positive economics deals with what is and what we have. The other type of economics is called normative statements. This deals with what we should receive instead of what is and deserved to some extent. It's our scarce resources that determine our allocation of resources and how we use our resources and time. This is where opportunity costs come in, giving up something to do something. A successful business or country never ignores opportunity costs. We must ensure that we have a comparative advantage instead of the absolute advantage. Our resources must be used to achieve maximum output. Comparative is met when we have fewer opportunity costs to make some certain products than the other person or entity.

My initial understanding was scarcity was oil potentially running out, but we have so much of it that you can always find more with techniques such as fracking. Now it's obvious to me, one of our most scarce resources is time. You cannot avoid the 8,760 hours in a year. I understand that people have unlimited wants but limited resources. Everything has a cost and we must make a choice as we don't have unlimited farms, factories workers, etc. scarcity forces choices and this ties in with opportunity cost, for every gun made, a theft from the hungry is made. The opportunity cost not being used to feed the poor, but to make guns. And I find it easy to understand no one can have everything choices must be made on benefits. If I'm going to school, imp giving up making cash, as I'm giving up money for an education, I value education more. Scarcity is also related to the invisible hand. As it's an achievement that leads free markets and capitalism through competition for scarce resources.

My understanding of the invisible hand is a person neither intends to promote public interest and does not know how much he is promoting it. Only intending on his own gain. Without being his intention a person can be lead by the invisible hand to do good for society by pursuing one's own self-interest. Going into equity and efficiency the invisible hand does ensure both equity and efficiency. People work in their selfish ways to maximize profit while also contributing to the economy as a whole. It can also be argued that as the invisible hand wants to ensure efficiency, it cannot guarantee efficiency, because it can fail to produce an efficient allocation of resources, which in turn lead to a market failure. It can also be argued that it can't guarantee equity because not everyone gets a fair price. The way I like to remember efficiency is with a real-life example, like a reduction in the number of workers needed to produce a particular good for a particular amount. Equity refers to the ownership interest in an asset, for example, if a person owns a house with a market value of $800,000 and owes $100,000 on the mortgage leaving a $700,000 equity in the home.

It can be predicted that if the price of beef increases - ceteris paribus-the quantity of beef demanded by buys will decrease. In other words, if the price of beef increases, then the quantity of beef increases, then the quantity of beef demanded will decrease because all things have to be equal. In-class lecture thought me all other things remaining the same. Economists use ceteris paribus to determine the effect of a factor when all other factors have been held the same and helps simplify the study and get a more refined data set.

Economists deal with many issues that pertain to assuring that both a countries domestic output is efficient and that there is an effective trade balance. This means that there are a balance and limit on the amount of imports. Also, this means home production must be able to meet export demands. There are many factors that affect the production of goods and their effect on shifting the production possibilities frontier. This involves evaluating every detail including knowing the products and any close substitutes and compliments. It also involves knowing how an action or other external force will affect demand. This is called price elasticity; Substitutes are products that can replace any given product or service. An example of this would be Coke and Pepsi. The presence of substitutes affects price elasticity because if there are other options, then any change to the price or quality of the product will cause a shift of the demand curve. O course, price is a huge reason why the demand for a product decreases or increases yet it doesn't shift the curve because of the price only. This price change will cause a domino effect that will end with the shifting of the demand curve because it will cause an increase or decrease in demand of the substitute good if the price change is either lower or higher respectively. This price change serves as a catalyst that will change people's desire to spend more money on a more expensive product and that will instead choose to buy the substitute good for cheaper or buy more of the desired product. The change in the price of actual products will not shift the demand curve yet the change of the price of substitutes will because it serves to change people's purchasing behavior. On the other hand, compliments serve to boost demand when there is a decrease in price. The use of complementary goods is dependent upon another product. An example of this would be hot dogs and buns. If the price of hotdogs decreases then, conversely, the demand for hot dog buns will increase because of this change in price. In this scenario, the decrease in price will cause a positive shift in the demand curve because of people's desire and willingness to buy more buns. This is an example of a demand shifter. There are a few other demand shifters. The shifters of the demand curve are changes in expectations, disposable income, price of substitute goods and complements, tastes and preferences, and population size and composition. Changes in income affect the demand curve because if income is lower then people tend to save any extra income instead of wasting it. Disposable income is minimized and spending is lower. This also causes people to see a perceived value of things and distinguishing between what is necessary and what is a relative luxury. The lower the income, the higher the saving and avoidance to spend. An example of this would be if someone needs to buy some medication and it is relatively expensive, that doesn't mean that someone won't buy the medication just because it is expensive. It is necessary. Other factors that contribute to spending and demand are having a price ceiling and price floor. Having a price ceiling is a limit on the price of the product this is a government-imposed idea that is meant to protect consumers from unfair pricing and other conditions that may be malicious or obscure. This affects demand because if there is a price ceiling there is a limit on profit on a unit-to-unit basis. The other factor is the price floor. This price floor was created to encourage competition and affect consumers' willingness to pay because sometimes this new price may be higher than the original price. This causes a negative impact on a product that has a less than wanted perceived value. Many factors contribute to economic prosperity and certainly do help assure that information is analyzed and implemented into an economic and business plan.

I need help writing a purpose for a chemistry experiment. I feel I was always do a great job, but my professor always disagrees and Iâm out of ideas. The professor wants us to summarize the introduction, and summarize what you will do in each section of the experiment and state how this work will support the goal of this experiment being longer than 1/2 a page. Please, please help me right a better purpose for the experiment below. Thanks.

Experiment 9 Molecular Weight Determination of a Pure Substance Using the Ideal Gas Equation.

Introduction:

The purpose of this experiment is to determine the molecular weight of a volatile, essentially non-polar liquid. An excess amount of pure unknown volatile liquid will be placed into a flask, whose volume will also be determined. The flask will be placed into a hot water bath, whose temperature corresponds to the temperature of the gas in the flask. The liquid will evaporate, driving out the air while the excess liquid evaporates. The pressure of the gas in the flask will correspond to the atmospheric pressure. After the excess unknown liquid has been allowed to evaporate, the flask will be stoppered, cooled, and weighed to determine the grams of the unknown liquid that will be present at the temperature of the water bath as a gas. In this experiment the ideal gas equation will be used PV = nRT = (g/M)RT where R = 0.0821 L*atm/mol*K, T = temperature in K, P = pressure in atm, V = volume in liters, n = moles of gas, g = grams of gas, and M = molecular weight of gas (in units of g/mole). Solving for the molecular weight, M: M = gRT/ PV.

If the molecular weight of a gas is to be determined, the m, T, P, and V must be determined experimentally in the lab. Even though the ideal gas equation is only an approximation of the behavior of gases, molecular weights can still be obtained within 5% of the correct values, as long as volatile non-polar compounds or compounds with only slight amount of polarity are used. For example, C, H, compounds as CH₄ are essentially non-polar, whereas compounds as H₂O are highly polar. Hence, the ideal gas equation would not be a good approximation for describing the behavior of gaseous water.

Procedure:

At the very beginning of the period get a one-liter beaker. Put about 800 mL (your instructor will tell you the exact amount needed) of tap water into the one-liter beaker. Put the one-liter beaker with water onto the hot plate. Set the heat setting of the hot plate to the maximum value. The water in the beaker should be boiling very lightly prior to doing the actual experiment. Therefore, after the water starts boiling in the hot water bath, it may be necessary to cut the heat setting back from highest value. This will take some time. While the water is heating, get the rest of the things needed for this experiment. The setup is shown in figure 1. Record the barometric pressure (in torr to one decimal place). Obtain the rest of the setup consisting of a 250 ml flask, properly prepared rubber stopper with glass tube and aluminum foil, a no-hole rubber stopper, thermometer, and glass stirring rod.

Make sure the 250 mL Florence (or Erlenmeyer) flask is dried (if it is not dry, rinse with 5 mL of acetone, pour off the acetone into the waste bottle in the hood, and then clamp the 250 mL Florence flask onto the ring stand in the inverted position to allow the last traces of acetone to drain out and evaporate. Place the dry no-hole stopper on the flask and weight the flask with the rubber stopper on the balance to 3 decimal places. Record this weight for the weight of the flask plus rubber stopper and moist air. Place 5 mL with a graduated cylinder of unknown liquid into the flask. Place the one-hole rubber stopper, with tube and aluminum foil in the flask. This one-hole stopper, which contains a glass tube that sticks out on the top by 3 mm and is flush with the bottom of the stopper, is covered with aluminum foil with a hole punched into the bottom where the glass tube is. This one-hole rubber stopper is already prepared for you. Push it down firmly into the flask. Remove it. Do this 2-3 times to smooth out the aluminum foil so that the stopper will go down into the flask as much as possible. Then push the stopper down so that it fits snugly but not too tightly to allow it to be removed while the flask is hot. Clamp the flask about the top lip of the Florence flask. That is, the center of the clamp goes about the rim of the flask. Push the flask as far down into the water bath as possible while holding the end of the clamp with your other hand. It is important to be sure that the water in the water bath is always at least 5 mm above there the bottom of the stopper is in the flask. More water may have to be added as some of the water evaporates during the duration of this experiment. (A beaker with hot water (extra) should be present in the hood. One or two of these beakers of hot water should be enough for everyone.) If the water level is not kept to its proper height, the liquid will condense in the upper part of the flask and the excess liquid will never be removed. Be sure that the aluminum foil on top makes a protective wind breaker for the short glass tube sticking out of the rubber stopper so that condensation does not occur there also. As the liquid evaporates from the flask, mix the water in the water bath occasionally and check to see that the temperature remains constant. Record the temperature value of the water bath as the temperature of the gas in the flask for the temperature of the gas would have equilibrated to the temperature of the water bath. After all the liquid has evaporated (takes 2-5 mins for the liquid to evaporate.) from the flask (check carefully that all of the liquid has evaporated-since observing when all the liquid has been evaporated maybe difficult, you should carefully shake slightly the clamp holding the Florence flask to observe the movement of the unknown liquid and when it has disappeared) and none is condensed on the surface walls; (if condensation occurs, be sure all precautions mentioned above are taken) then (these next several steps are to be done quick) remove the rubber stopper with the glass tubing and aluminum foil without excessive shaking. There could be a condensed liquid droplet or two in the glass tube that is not visible. The droplets could drop back into the flask and cause a false high reading for the measured weight of gas in the flask. Immediately replace the rubber stopper (with the glass tube and aluminum foil) with the no-hole stopper, which was used when the flask was originally weighed. This step must be performed quickly to prevent the unknown gas vapors from escaping and being replaced by moist air. Place the no-hole rubber stopper in the Florence flask firmly. Remove the flask from the bath and again check to be sure that the no-hole rubber stopper is firmly in place. Cool the flask by running tap water over the flask for 30-60 seconds. If the stopper is not fitted firmly, air will enter the flask as the liquid inside the flask condenses. As the gas cools and changes to the liquid state, a partial vacuum is created inside the flask. Hence, air will enter the flask if the rubber stopper is not fitted firmly. Completely dry the flask and weigh it on the balance to three decimal places. Record the weight of flask plus stopper and unknown gas.

Repeat this entire procedure a second time and record the date. After, second trial, completely fill the flask with distilled water. Place the no-hole rubber stopper in the flask allowing the excess water to overflow. Wipe the outside completely dry. Then measure the volume of the water in the flask by pouring water into a graduated cylinder. Record this volume.
