Answer :

GinnyAnswer

Final answer:

The detailed answer provides balanced chemical equations and ionic equations for various acid reactions with metals and oxides.


Explanation:

Balance the chemical equations:

  1. Mg + H2SO4 → MgSO4 + H2
  2. CaCO3 + 2HCl → CaCl2 + CO2 + H2O
  3. ZnO + 2HCl → ZnCl2 + H2O
  4. 2KOH + HNO3 → KNO3 + 2H2O

Write the ionic equations for each reaction:

  1. Mg + 2H+ + SO4²- → Mg²+ + SO4²- + H2
  2. CaCO3 + 2H+ + 2Cl- → Ca²+ + 2Cl- + CO2 + H2O
  3. ZnO + 2H+ + 2Cl- → Zn²+ + 2Cl- + H2O
  4. 2K+ + 2OH- + H+ + NO3- → 2K+ + NO3- + 2H2O
