Richard and Brooke's teacher tells them to place 30 marbles in an 8-inch
baking pan to make a model. She tells them that each marble represents
a water molecule in the liquid state. Then she asks them to move their
model to show what happens to the liquid water molecules when heat is
added. What do Richard and Brooke do to show this?
They spread the marbles to the edges with their hands.
They tilt the pan so the marbles move to one side of the pan.
They push the marbles to the center of the pan with their hands
They gently shake the pan causing the marbles to move back and forth.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
