Write two molecular reaction equations that correspond to the short ion-molecular equation MgO + 2H + = Mg2 + + H2O

1) MgO + 2HCl -> MgCl2 + H2O;

The complete ionic equation, in this case, is written as follows:

MgO + 2H (+) + 2Cl (-) -> Mg (2+) + 2Cl (-) + H2O;

The abbreviated ionic equation will look like this:

MgO + 2H (+) -> Mg (2+) + H2O.

2) MgO + 2HNO3 (diluted) -> Mg (NO3) 2 + H2O;

The complete ionic equation of this reaction is written as follows:

MgO + 2H (+) + 2NO3 (-) -> Mg (2+) + 2NO3 (-) + H2O;

The abbreviated ionic equation for this reaction is:

MgO + 2H (+) -> Mg (2+) + H2O.

Both reactions illustrate the reaction of a basic oxide with an acid, and lead to the formation of salt and water.
