Two identical blocks are heated to different temperatures. The blocks are placed so that the touch, and heat begins to flow between the blocks. The pair of blocks is insulated, so no
energy escapes.

possible?

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

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.

you gotta add the following molecules so we can give u an answer
