Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An ____ reaction is when more energy is released than is absorbed. This energy can be in the form of light, heat, electricity, etc.
A
endothermic
B
endergonic
C
exothermic
D
exergonic
Explanation: 

Detailed explanation-1: -Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.

Detailed explanation-2: -Exergonic reactions release energy The energy level of the products is lower than the energy level of the reactants. Energy is released in this reaction. The amount of energy released during the reaction is termed G, which is less than zero.

Detailed explanation-3: -In any chemical reaction, energy is required to break the bonds in reactions, and energy is released when new bonds form after the reaction.

Detailed explanation-4: -In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill). In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill).
