Question

MgO + ____ = Mg(No3)2 + _____

Answer 1

MgO+NO2+O2= Mg(NO3)2

Answer 2

MgO+2HNO3=Mg(NO3)2+H2O

Answer 3

The balanced chemical equation for the reaction between MgO and HNO3 to form Mg(NO3)2 and H2O is:

MgO + 2HNO3 → Mg(NO3)2 + H2O

So, you would need 2 moles of HNO3 to react with 1 mole of MgO to produce 1 mole of Mg(NO3)2 and 1 mole of H2O.
