Balancing Chemical Equations and Identifying Types of Reactions

1) CO2 + Ca(OH)2: - The balanced equation is: CO2 + Ca(OH)2 → CaCO3 + H2O - Type of reaction: This is a double displacement reaction.

2) KOH + H2SO4: - The balanced equation is: 2KOH + H2SO4 → K2SO4 + 2H2O - Type of reaction: This is a double displacement reaction.

3) CaO + NaOH: - The balanced equation is: CaO + 2NaOH → Na2O + Ca(OH)2 - Type of reaction: This is a double displacement reaction.

4) KOH + Ca(OH)2: - The balanced equation is: 2KOH + Ca(OH)2 → Ca(OH)2 + 2KOH - Type of reaction: This is a double displacement reaction.

5) H2SO4 + ZnO: - The balanced equation is: H2SO4 + ZnO → ZnSO4 + H2O - Type of reaction: This is a double displacement reaction.

6) HNO3 + BaO: - The balanced equation is: 2HNO3 + BaO → Ba(NO3)2 + H2O - Type of reaction: This is a double displacement reaction.

7) SO3 + HCl: - The balanced equation is: SO3 + 6HCl → 2H2O + 6Cl + S - Type of reaction: This is a synthesis reaction.

8) SO3 + KOH: - The balanced equation is: SO3 + 2KOH → K2SO4 + H2O - Type of reaction: This is a double displacement reaction.

9) H2O + CO2: - The balanced equation is: H2O + CO2 → H2CO3 - Type of reaction: This is a synthesis reaction.

10) Li2O + H2O: - The balanced equation is: Li2O + H2O → 2LiOH - Type of reaction: This is a synthesis reaction.
