Question

chemical equation to show a reaction that takes place by absorption of sound energy​

Answer 1

Answer:

Assertion

Chemical reactions that release energy in the form of heat, light or sound are called exothermic reactions

Reason

Reactions that absorb energy or require energy in order to proceed are called endothermic reactions

Answer 2

Explanation:

Chemical reactions that release energy in the form of heat, light or sound are called exothermic reactions

Example : Mixture of sodium and chlorine to yield table salt

(s)→NaCl(s)+ 411 kJ of energy.

Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example : In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
