A 1000 L tank contains 500 L of water with a salt concentration of 10 g/L. Water with a salt concentration of 7070 g/L flows into the tank at a rate of 8080 L/min. The fluid mixes instantaneously and is pumped out at the rate of Rout=40Rout=40 L/min.

Let y(t)y(t) denote the quantity of salt in the tank at time tt.

Find the salt concentration when the tank overflows.

(Use decimal notation. Give your answer to one decimal place.)

The concentration of salt is g/L.

Choose at least four (4) items from each of the three (3) lists below. Weave these four items into three related or scenes to create a story.

For instance, you might decide to write a paper about tracks in the snow that lead to a diamond necklace that hangs from a graveyard tombstone.

At that point, a raspy laugh breaks the silence of the night, and mysteriously the tracks in the snow end abruptly.

NOTE: Your submission must contain at least three scenes and follow the general rules for 'scene.' Each scene must have a beginning, middle, and end. Each scene should do one or more of the following:

a. Provide exposition

b. Describe character

c. Advance the plot

Choose at least four items from each list and write your scenes.

1.

a poisoned drink

a howling collie

a deserted farmhouse

a purse with $100

a forest fire

a yellow Cadillac

a set of drums

a motorcycle

an airline ticket

a screaming burglar alarm

a broken window

tracks in the snow

a blind guitarist

2.

a tube of lipstick

a diamond necklace

a ringing phone

a face at the window

a rattlesnake

a barber

a newspaper ad

a single glove

a white cat

a piercing scream

a swarm of bees

a glass of champagne

a blonde wig

a dead tree

a mannequin

3.

a pouch of tobacco

a palomino stallion

a walking cane

a garden path

a silver teapot

a moving shadow

a ferris wheel

a picnic basket

a bird

a lace curtain

a raspy laugh

a glowing fireplace

Briefly explain how each of your scenes follows the general rules for 'scene.'

You have been asked to place a paper and three contemporary items from your generation in a time capsule that will be placed in a cornerstone of a public building. This cornerstone will be opened in the year 2100, at which time it will be read by the people of the community.

Think about two things:

a. What information about your generation do you want future generations to know? This will be the focus of your paper.

b. What items will you choose to place in the time capsule? Why did you choose these items?

Write your paper as a scene or a series of scenes. Remember, each scene should have a beginning, a middle, and an end. Also remember that each scene should do one or more of the following

a. Provide exposition

b. Describe character

c. Advance the plot

Explain how each one of these elements can be found in your scene or scenes.

3. A student dissolved a 0.139g sample of oxalic acid, H,C,O,, in water in an Erlenmeyer flask. Then the student titrated the H,C,O, solution in the flask with a solution of KMnC which has a dark purple color. The balanced chemical equation for the reaction that occurred during the titration is shown below.

Identify the species that was reduced in the titration reaction.

Justify your answer in terms of oxidation numbers.
