Q: Jennifer and Justin are examining the principle of chemical equilibrium in their second year organic chemistry course. They are performing a reaction that involves hydrogen gas and glucose as the starting reactants, and the products formed in the reaction are carbon dioxide and oxygen gas. Jennifer and Justin add the materials, and then wait until the reaction has reached equilibrium. Afterwards, Jennifer removes glucose from her reaction mixture, while Justin removes carbon dioxide from his reaction mixture. Which person's reaction, Jennifer's or Justin's, will begin producing more carbon dioxide?
A: Justin's

Question: Mark decides he want a cold drink and puts a bottle of warm water in his freezer. By doing this he makes the water colder and as water cools its density increases eventually freezing and becoming a solid, Ice. After a while mark forgets that he put the bottle of water in the freezer. He eventually remembers and comes back to check and the bottle of water is frozen solid. Because of this he leaves the bottle out on his kitchen counter for a few hours and returns to a nice cold bottle of water. Will lowering the temperature of water cause it's density to increase or decrease?
Answer:
increase
