Answer 2

1) AgNO3 + HBr

To write the molecular, complete ionic, and net ionic equations for the reaction between AgNO3 and HBr, we need to first identify the formulas of the reactants and products.

The reactants are: - AgNO3 (silver nitrate) - HBr (hydrobromic acid)

The products will be: - AgBr (silver bromide) - HNO3 (nitric acid)

Now let's write the equations:

Molecular Equation: AgNO3 + HBr -> AgBr + HNO3

Complete Ionic Equation: Ag+(aq) + NO3-(aq) + H+(aq) + Br-(aq) -> AgBr(s) + H+(aq) + NO3-(aq)

Net Ionic Equation: Ag+(aq) + Br-(aq) -> AgBr(s)

2) MgO + H2SO4

For the reaction between MgO and H2SO4, let's determine the formulas of the reactants and products.

The reactants are: - MgO (magnesium oxide) - H2SO4 (sulfuric acid)

The products will be: - MgSO4 (magnesium sulfate) - H2O (water)

Now let's write the equations:

Molecular Equation: MgO + H2SO4 -> MgSO4 + H2O

Complete Ionic Equation: Mg2+(aq) + O2-(aq) + 2H+(aq) + SO4^2-(aq) -> MgSO4(aq) + H2O(l)

Net Ionic Equation: Mg2+(aq) + O2-(aq) + 2H+(aq) + SO4^2-(aq) -> MgSO4(aq) + H2O(l)

Please note that the net ionic equation is the same as the complete ionic equation in this case.
