Question

In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why?(1 point)ResponsesIt is exothermic because heat needs to be released by the reactants to form the products.It is exothermic because heat needs to be released by the reactants to form the products.It is endothermic because heat needs to be released by the reactants to form the products.It is endothermic because heat needs to be released by the reactants to form the products.It is endothermic because heat needs to be absorbed by the reactants to form the products.It is endothermic because heat needs to be absorbed by the reactants to form the products.It is exothermic because heat needs to be absorbed by the reactants to form the products.It is exothermic because heat needs to be absorbed by the reactants to form the products.

Answer 1

The correct response is: It is endothermic because heat needs to be absorbed by the reactants to form the products.

This is because breaking water into hydrogen and oxygen requires a significant amount of energy input (in the form of heat) to overcome the bonds in the water molecules, which classifies the reaction as endothermic.
