100.0 g of hexane accidentally spills into 1.00 L of water. Generally speaking, hexane and water are immiscible and can easily be separated. However, the solubility of hexane is reported to be 0.0011 g hexane per 100 mL of water at 25 oC. What mass of hexane will dissolve in the water?

Hi Iâve been struggling with my lab report and in need of some help. Here is everything you might need the lab report and data recorded in my notebook. I need help in the report questions please

QUALITATIVE STUDIES OF OXIDATION-REDUCTION REACTIONS Your objectives in this experiment include determining the products means of experimental tests, experimentally determining the relative ability of chlorine, and iodine to act as oxidizing agents, and designing an experiment to test an of a chemical reaction by bromine d rank a group of in order of their strength as reducing agents. All these objectives will require you to think logically in both your approach and your analysis of the results. Pre-Lab Questions: 1. In this lab you will be mixing hexane with aqueous (water) solutions. Which layer will be the water layer - top or bottom? Explain what property allows you to determine this. 2. Write a balanced chemical equation for the reaction of calcium metal with hydrochloric acid. What visible changes do you expect to see? Safety and Disposal: 1. Hexane is a volatile and flammable solvent. No open flames during this laboratory. When corked test tubes are shaken, pressure may develop, especially when a volatile solvent is one of the components. Remember to release the pressure intermittently by removing the cork slowly 2. Hydrochloric acid is corrosive. Wash your hands well with soap and water after working with it. 3. All solutions containing hexane must be placed in a container for recovery. Do not discard hexane down the sink. Do not put metals in the hexane recovery container. Part 1: The halogens Non-metals, such as the halogens, have relatively high electron affinities and as a result tend to react by gaining electrons, which we call becoming reduced, to form anions. In this experiment we will use the difference in solubility of the halogens (Cl2, Br2, and 12) as compared to the halides (Cr'. Br, and I') to test the reactivity of the elements The elemental halogens are non-polar and therefore are not very soluble in water. As a resul solutions of the halogen s in water are not very brightly colored. However, if an aqueous solution is mixed with a non-polar solvent, such as hexane, C&H14, the halogen is usually ferentially extracted into the non-polar solvent. Since the non-polar solvent is water, the halogen color is easily visible as a not miscible with separate colored layer

1. The thermite reaction is performed using 8.6g Fe2O3 and 1.8g powdered Al metal/

a. Which reactant is the excess?

b. How many grams of excess reactant are left over?

c. How many grams of aluminum oxide can be produced?

2. The reaction of 5.0g of CuSo4 with excess sodium hydroxide produced 2.6g of Cu(OH)2. What percent yield of Cu(OH)2 was obtained?

3. Approximately 46.4 grams of sodium acetate (82.0 gm/mol) will dissolve in 100 grams of water at 20 degrees Celcius. If 2.75 mol NaCH3COO is dissolved in 355 g of water, the solution will be:

A. dilute

B. concentrated

C. saturated

D. supersaturated

4. Answer the following as true or false:

A. NaCl(aq) has a greater surface tension from H20

B. CH4 is more polarizable than CBr4

C. C12H6 is more viscous than C5H12

D. Compared to methanol, Bromine is more soluble in hexane.

E. Water rises in a capillary tube due to the fact that cohesive forces between the water molecules are stronger than the adhesive forces between water and the glass.

1, A solution is prepared by mixing 25 mL pentane (C5H12, d = 0.63 g/cm3) with 47 mL hexane (C6H14, d = 0.66 g/cm3). Assuming that the volumes add on mixing, calculate the mass percent, mole fraction, molality, and molarity of the pentane. Mass percent = % Mole fraction = Molality = mol/kg Molarity = mol/L 2, A solution is made by dissolving 22.4 g urea (CH4N2O), a nonelectrolyte, in 254 g water. (The vapor pressure of pure water is 23.8 torr at 25Â°C and 71.9 torr at 45Â°C.) Calculate the vapor pressure of this solution at 25Â°C. Vapor pressure = torr Calculate the vapor pressure of this solution at 45Â°C. Vapor pressure = torr 3,A solution is prepared by dissolving 22.6 g urea, (NH2)2CO, in 150.0 g water. Calculate the boiling point of the solution. Urea is a nonelectrolyte. (This problem requires values in your textbook's specific appendices, which you can access through the OWLv2 MindTap Reader. You should not use the OWLv2 References' Tables to answer this question as the values will not match.) Boiling point = Â°C 4, What mass of glycerin (C3H8O3), a nonelectrolyte, must be dissolved in 200.0 g water to give a solution with a freezing point of â2.30Â°C? (This problem requires values in your textbook's specific appendices, which you can access through the OWLv2 MindTap Reader. You should not use the OWLv2 References' Tables to answer this question as the values will not match.) Mass = g
