Answer 2

2Mg+O2=2MgO
Ag+HCl-реакція не відбуваеться 
Na+2H2O=2NaOH+H2
Zn+CuCl=
Cu+H2SO4-реакція не відбуваеться 
Hg+H2O=

Answer 3

Balanced Chemical Equations in Aqueous Solutions

Here are the balanced chemical equations for the given reactions in aqueous solutions:

1. Mg + O2 = MgO - This is the reaction between magnesium (Mg) and oxygen (O2) to form magnesium oxide (MgO) [[1]].

2. Ag + HCl = AgCl + H2 - This is the reaction between silver (Ag) and hydrochloric acid (HCl) to form silver chloride (AgCl) and hydrogen gas (H2) [[2]].

3. Na + H2O = NaOH + H2 - This is the reaction between sodium (Na) and water (H2O) to form sodium hydroxide (NaOH) and hydrogen gas (H2) [[3]].

4. Zn + CuCl2 = ZnCl2 + Cu - This is the reaction between zinc (Zn) and copper chloride (CuCl2) to form zinc chloride (ZnCl2) and copper (Cu) [[4]].

5. Cu + H2SO4 = CuSO4 + H2O + SO2 - This is the reaction between copper (Cu) and sulfuric acid (H2SO4) to form copper sulfate (CuSO4), water (H2O), and sulfur dioxide (SO2) [[5]].

6. Hg + H2O = HgO + H2 - This is the reaction between mercury (Hg) and water (H2O) to form mercury(II) oxide (HgO) and hydrogen gas (H2) [[6]].

Please note that these balanced equations represent the stoichiometry of the reactions, indicating the relative amounts of reactants and products involved.
