Substances given: MgO, CO2, ZnO, CuCL2, NaCL, H2S. Which of these substances will react

Substances given: MgO, CO2, ZnO, CuCL2, NaCL, H2S. Which of these substances will react with KOH? Write equations in molecular and ionic form

1.2KOH + CO2 = K2CO3 + H2O

2K + 1 + 2OH1- + CO2 = 2K + 1 + CO32- + H2O (full ionic equation);

2OH1- + CO2 = CO32- + H2O (abbreviated ionic equation);

2. KOH + ZnO = KZnO2 (the reaction proceeds in the solid phase);

3.2KOH + H2S = K2S + H2O

2K + 1 + 2OH1- + 2H + 1 + S-2 = 2K + 1 + S-2 + H2O (full ionic equation);

2OH1- + 2H + 1 = 2K + 1 + S-2 + H2O (abbreviated ionic equation);

4.2KOH + CuCl2 = 2KCl + Cu (OH) 2

2K + 1 + 2OH1- + Cu + 2 + 2Cl-1 = 2K + 1 + 2Cl-1 + Cu (OH) 2 (complete ionic equation);

2OH1- + Cu + 2 = Cu (OH) 2 (abbreviated ionic equation);
