Write the balance equation with state symbole
a)Solution of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride.
b)Sodium hydrixide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.
The addition of stoichiometric coefficients to the reactants and products includes balancing chemical equations. It is significant since the law of conservation of mass and the law of constant proportions must be enforced by a chemical equation, which is the same number of atoms of the element on the reactant side and the product side of the equation must remain.
In the hit and trial method of balancing chemical equations, experiments are carried out by using the least whole number coefficient to balance the chemical equation. Hence it is known as the hit and trial method.
-Count the number of times on both sides that an element occurs.
-First, an element with the least occurrence frequency is balanced.
-Metallic elements are matched first because two or more elements have the same frequency.
a) BaCl2 + Na2SO4 ---------> BaSO4 + 2NaCl
b) NaOH+HCl ---------> NaCl + H2O
