Astudent performs a reaction twice. in the second trial, he increases the temperature of the reaction and notes that the reaction happens more quickly. the student concludes that this means the reaction was endothermic. what is wrong with the student's reasoning? a. higher temperature increases reaction rates for both endothermic and exothermic reactions. b.an endothermic reaction would not speed up at higher temperatures. c.temperature does not affect the rate of a reaction. d.the higher temperature in the second trial actually lowered the activation energy of the reaction.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
