In an exothermic reaction, why does the chemical reaction give off energy in the form of heat or light? A) Energy is created in
the chemical reaction. B) The reactants are more stable than the products. C) The products are more stable than the reactants. D) The reactants have less energy stored in the bonds than the reactants.
C) The products are more stable than the reactants.
Explanation:
Exothermic reaction are reactions that dissipate energy to the environment. In exothermic reactions the reactant are at higher energy than the product therefore they release more heat to the surroundings. The ability and haste for exothermic reaction to go into reaction and release heat contributes to the stability of the product than the reactant .
Example of Exothermic reactions includes the combustion of methane ;
Physical changes are changes that do not alter the identity of a substance. Chemical changes are changes that occur when one substance is turned into another substance.
