Areaction in which the reactants have more energy than the products is always a(n) endothermic decomposition replacement exothermic

In exothermic/exergonic reactions, reactants have greater energy(Gibbs-Free Energy) than the products. This energy determines how much mechanical work a system can do

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
