Question
Balance the following chemical equation.
\[\ce{NaCl + AgNO3 -> AgCl + NaNO3}\]
Solution
The number of atoms of elements in reactants and products is equal. It does not require any further balancing.
Since all the elements are balanced, the final balance equation is:
\[\ce{NaCl + AgNO3 -> AgCl + NaNO3}\]
The given equation is already balanced.
