GENERAL KNOWLEDGE

Detailed explanation-1: -In chemistry, coefficient indicates the number of atoms (or moles) of a particular substance present in a reaction. Stoichiometry involves the calculation of relative ratios between products and reactants in a reaction using a balanced equation.

Detailed explanation-2: -The coefficients of a balanced chemical equation tell us the relative number of moles of reactants and products. All stoichiometric calculations begin with a balanced equation. Balanced equations are necessary because mass is conserved in every reaction.

Detailed explanation-3: -The stoichiometry of a reaction describes the relative amounts of reactants and products in a balanced chemical equation.

Detailed explanation-4: -The coefficients indicate the number of each substance involved in the reaction and may be changed in order to balance the equation.

Detailed explanation-5: -stoichiometric ratio: The ratio of the coefficients of the products and reactants in a balanced reaction. This ratio can be used to calculate the amount of products or reactants produced or used in a reaction.
