Question

Quote certain examples of chemical reactions from daily life.

Answer 1

Hint:To answer this question we should know what a chemical reaction is. A chemical reaction is a reaction in which one or chemical compounds react to form new chemical compounds. This process sometimes requires the input of energy or sometimes liberates the energy. The compounds that react are known as reactants and the compounds formed are known as products.

Complete step-by-step answer:During chemical reactions, the compounds chemically transform. The conversion of one chemical compound into another can be in one step or may include more than one step.

Photosynthesis is an example of a chemical reaction through which plants convert carbon dioxide into oxygen. The chemical equation of photosynthesis is as follows:

\[{\text{6C}}{{\text{O}}_{\text{2}}}\,{\text{ + }}\,{\text{6}}{{\text{H}}_{\text{2}}}{\text{O}}\,{\text{ + }}\,{\text{light}} \to \,{{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}\,{\text{ + }}\,{\text{6}}{{\text{O}}_{\text{2}}}\]

Photosynthesis produces carbohydrates and oxygen. Oxygen is used for respiration and carbohydrates are consumed in the form of fruits or vegetables.

Another example is cellular respiration when we consumed food. We get carbohydrates, vitamins, etc. The carbohydrate is used for cellular respiration. Cellular respiration converts the carbohydrate into energy. The chemical equation of cellular respiration is as follows:

\[{{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}\,{\text{ + }}\,{\text{6}}{{\text{O}}_{\text{2}}} \to \,{\text{6C}}{{\text{O}}_{\text{2}}}\,{\text{ + }}\,{\text{6}}{{\text{H}}_{\text{2}}}{\text{O}}\,{\text{ + }}\,{\text{energy}}\]

The burning of the candle, match, and wood for cooking is also an example of daily life chemical reactions.

Note: The burning in presence of oxygen is known as combustion. The products of the combustion of hydrocarbons are carbon dioxide and water. A chemical reaction is represented in form of a chemical equation. A chemical equation includes the reactant on the left-hand side and products on the right-hand side and a right arrow which tells the conversion of reactants into products.
