Particles of a liquid A. Are free to move in a container but remain in close contact with one another
B. Are tightly packed together and stay in a fixed position
C. Have no viscosity
D. Decrease in volume with increasing temperature

A

Explanation:

B. That's a solid

C. Liquid is the only thing that can have viscosity

D. Not necessarily the case

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
