Write out the balanced equation for the reaction that occurs when Ca and Al(NO3)3 react together. Is it Ca + Al (NO3)2 yields Ca(NO3)2 + Al? Why or why not?

Answer: -

The chemical reaction that is occurring is

Ca + Al(NO₃)₃ → Al + Ca(NO₃)₂

Balancing the nitrogen on both sides

Ca + 2 Al(NO₃)₃ → Al + 3 Ca(NO₃)₂

Balancing the calcium on both sides

3 Ca + 2 Al(NO₃)₃ → Al + 3 Ca(NO₃)₂

Balancing the aluminium on both sides

3 Ca + 2 Al(NO₃)₃ → 2 Al + 3 Ca(NO₃)₂

We see oxygen is balanced.

The balanced chemical equation for the reaction is

3 Ca + 2 Al(NO₃)₃ → 2 Al + 3 Ca(NO₃)₂
