Answer 2

Chemical Equations and Reactions

Here are the balanced chemical equations for the given reactions along with the names of the reactants and products:

1. MgO + HNO3 → Mg(NO3)2 + H2O - Reactants: Magnesium oxide (MgO) and Nitric acid (HNO3) - Products: Magnesium nitrate (Mg(NO3)2) and Water (H2O)

2. Ca(OH)2 + Na2O → CaO + 2NaOH - Reactants: Calcium hydroxide (Ca(OH)2) and Sodium oxide (Na2O) - Products: Calcium oxide (CaO) and Sodium hydroxide (NaOH)

3. HCl + SO3 → H2SO4 - Reactants: Hydrochloric acid (HCl) and Sulfur trioxide (SO3) - Product: Sulfuric acid (H2SO4)

4. H2O → Na2O + H2O - Reactant: Water (H2O) - Products: Sodium oxide (Na2O) and Water (H2O)

5. P2O5 → K2O - Reactant: Phosphorus pentoxide (P2O5) - Product: Potassium oxide (K2O)

Please note that these equations are balanced, meaning that the number of atoms of each element is the same on both sides of the equation.
