Question

1. MgO + H2SO4 = 2. Ca(OH)2 + H2SO4 = 3. K2CO3 + H2SO4 = 4. Na2S + H2SO4 = 5. Ba(NO3)2 + H2SO4 =

Answer 1

Answer 2

Let's balance the chemical equations you provided:

1. MgO + H2SO4 = MgSO4 + H2O

2. Ca(OH)2 + H2SO4 = CaSO4 + 2H2O

3. K2CO3 + H2SO4 = K2SO4 + H2O + CO2

4. Na2S + H2SO4 = Na2SO4 + H2S

5. Ba(NO3)2 + H2SO4 = BaSO4 + 2HNO3

These balanced chemical equations represent the reactions between the given substances and sulfuric acid (H2SO4).
