Inside a calorimeter, two solutions are mixed and result in an endothermic reaction. which of the following best illustrates how this reaction affects the water in the calorimeter? (2 points)
select one:
a. the reaction has no effect on the water. the kinetic energy of the water molecules remains the same.
b. the reaction causes the temperature of the water to increase. the kinetic energy of the water molecules increases.
c. the reaction causes the temperature of the water to decrease. the kinetic energy of the water molecules decreases.
d. the reaction causes the temperature of the water to decrease. then, the water gains heat from the surroundings and the kinetic energy of the water molecules increases.

Which of the following is a compound? a. carbon b. oxygen c. hydrogen d. water

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
