Question

identify 6 chemical processes that can take place at home and investigate the heat changes that take place and determine whether its endothermic or exothermic

Answer 1

Answer:

In an exothermic reaction, ΔH is less than zero because the energy of the reactants is greater than the energy of the products. Energy is released in the reaction. For example:

H2(g)+Cl2(g)→2HCl (g)ΔH<0

In an endothermic reaction, ΔH is greater than zero because the energy of the reactants is less than the energy of the products. Energy is absorbed in the reaction. For example:
