    You don't normally do this, but you might start by balancing the complex ion which is NO3^-

    There are 2 of these on the right side of the arrow so make two on the left.

    CaO + 2HNO3 arrow Ca (NO3) 2 + H2O

    That looks balanced. Let's check it out.

    Species Ca H NO3 O

    Left 1 2 2 1 on the CaO

    Right 1 2 2 1 on the H2O
