Choose the best answer:

1. Balance the following chemical equation.

\(HNO_3\) + \(Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(H_2O\)

\(2HNO_3\) + \(2Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(2H_2O\)
\(2HNO_3\) + \(Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(3H_2O\)
\(2HNO_3\) + \(Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(2H_2O\)
\(2HNO_3\) + \(Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(2H_3O\)
\(HNO_3\) + \(Ca(OH)_2\) → \(Ca(NO_3)_2\) + \(2H_2O\)

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

Zinc + Silver nitrate → Zinc nitrate + Silver

\(Zn\) + \(2AgNO_3\) → \(Zn(NO_3)_2\) + \(2Ag\)
\(Zn\) + \(2AgNO_3\) → \(Zr(NO_3)_2\) + \(2Ag\)
\(Zn\) + \(AgNO_3\) → \(Zn(NO_3)_2\) + \(2Ag\)
\(Zn\) + \(2AgNO_3\) → \(Zn(NO_3)_2\) + \(Ag\)
\(Zn\) + \(2AuNO_3\) → \(Zn(NO_3)_2\) + \(2Ag\)
