Question

What is a chemical equation? Why are chemical equations balanced? Write a balanced chemical equation with state symbols for the following reaction
Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride.

Answer 1

Atoms of Elements on Reactant Side = Atoms of Elements on Product Side

Explanation:

• In the form of symbols and formulas, a symbolic representation of reaction with reactants on left and products on the right side is termed as Chemical Equation.

• Any Chemical Equation is Balanced, which shows the following principle of Law of conservation of Mass

• The number of atoms of elements on Reactant Side  = Number of atoms of elements on Product Side, which is the general condition for Balanced Equation.

The Balanced Chemical Equation for the Reaction is as under -  

$BaCl_2 + Na_2SO_4\geq BaSO_4 + 2NaCl$
