What mass is equal to 24.3 mold of gold chloride (AuCl3) ? **Show all work

Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity.

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? 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 exothermic 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.
