1. Balance the following chemical equation.

\(NaCl\) + \(AgNO_3\) → \(AgCl\)+ \(NaNO_3\)

\(NaCl\) + \(AgNO_3\) → \(AgCl\)+ \(NaNO_3\)
\(NaBr\) + \(AgNO_3\) → \(AgCl\)+ \(NaNO_3\)
\(NaCl\) + \(2AgNO_3\) → \(AgCl\)+ \(NaNO_3\)
\(NaCl\) + \(AgNO_3\) → \(AgCl\)+ \(2NaNO_3\)
\(2NaCl\) + \(AgNO_3\) → \(AgCl\)+ \(NaNO_3\)

2. Write the balanced chemical equations for the following reactions.

Aluminium + Copper chloride → Aluminium chloride + Copper

\(Al\) + \(3CuCl_2\) → \(2AlCl_3\) + \(3Cu\)
\(2Al\) + \(3CuCl_2\) → \(2AlCl_3\) + \(Cu\)
\(2Al\) + \(3CuCl_2\) → \(2AlCl_3\) + \(3Cu\)
\(2Al\) + \(3CuCl_2\) → \(2AlCl_3\) + \(3Ca\)
\(2Al\) + \(CuCl_2\) → \(2AlCl_3\) + \(3Cu\)
