Balance the following chemical equations.
(a) (b) (c) (d)

Answer:

When solving an equation for a chemical reaction, a balanced equation is one where the number of atoms for each element in the reaction, as well as the total charge, for both the reactants and products is the same.

(a) 2HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + 2H₂O

(b) 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

(c) NaCl + AgNO₃ → AgCl + NaNO₃

(d) BaCl₂ + H₂SO₄ → BaSO₄ + 2HCl
