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 ;

CH4(methane) + 2O2(oxygen molecule)  →  CO2(carbon dioxide) + 2H2O(water molecule) + heats

The reactant is at the left hand side while the product is at the right.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the right answer is c i just did the question.
