Suppose you are pouring a liquid into a beaker using a burette to cause a chemical reaction that will result in a color change. The initial reading of the liquid in the
burette was 15.2 mL and the final reading was 62.6 mL. What volume of liquid in the
burette was added to the beaker?

a is the answer to this question

explanation:

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.
