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 ;
the transition from water to steam is call evaporation.
Explanation:
water evaporates or vaporizes and turns into steam this typically happens when heat meets with the water. an example would be if you boil water steam will release from the pot, or when it rains, snows, etc (precipitation) the water evaporates and the ground dries.
Plant cells use chloroplast as kind of an extra mitochondria in a plant cell. They work together, when a chloroplast gets food through photosynthesis the mitochondria breaks down that food and distributes it through the cell.
