Question

define chemical equation? what is an unbalanced chemical equation called? which law governs the balancing of chemical equation? state it

Answer 1

chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. unbalanced chemical equation has unequal no. of atoms in the reactants and products. For ex. Mg + O2 ⇒ MgO. Law of conservation of mass governs the balancing of a chemical equation. According to this law matter can neither be created nor destroyed in a chemical reaction.

Answer 2

A. chemical equation is the symbolic representation of chemical reaction in the form of symbols and formulae ,in which , reactants are written on the left- hand side and products on the right - hand side.

An unbalanced chemical equation is also called skeletal equation ..until it gets balanced. unbalanced chemical equation means...that there are not equal no. of atoms on both sides.

"Conservation of mass" governs the balancing of chemical equation.
