Answer 2

The chemical equations you provided appear to be incomplete, as they are missing reactants in the first and third equations. However, I can help you balance the equations based on the information you provided. Here are the balanced chemical equations:

1. Reactant + SO3 → K2SO4 + H2O

2. K2O + Reactant → K3PO4 + H2O

3. Reactant + MgO → Mg(NO3)2

Please provide the missing reactants in the equations so that I can provide a more accurate and complete response.
