Answer 1

MgCo3+2HCl⇒MgCl2+ H2CO3(кислота и распадается на H2O и CO2)
Mg+Co3+2H+2Cl⇒Mg+2Cl+H2O+CO2
Co3+2H⇒H2O+CO2

2HNO3+Ba(OH)2⇒Ba(NO3)2+ 2H2O
2H+2NO3+ Ba+ 2OH⇒Ba+ 2NO3+2H2O
2H+2OH⇒2H2O

FeCl2+2AgNO3⇒Fe(NO3)2+ 2AgCl осадок 
Fe+2Cl+2Ag+2NO3⇒Fe+2NO3+2AgCl
2Cl+2Ag⇒2AgCl

Answer 2

Reaction 1: MgCO3 + HCl

The reaction between magnesium carbonate (MgCO3) and hydrochloric acid (HCl) can be represented by the following balanced chemical equation:

MgCO3 + 2HCl → MgCl2 + H2O + CO2

This is the complete ionic equation for the reaction:

Mg2+ + CO3^2- + 2H+ + 2Cl- → Mg^2+ + 2Cl- + H2O + CO2

And this is the net ionic equation, which shows only the species that are directly involved in the reaction:

Mg2+ + CO3^2- + 2H+ → Mg^2+ + H2O + CO2

Reaction 2: HNO3 + Ba(OH)2

The reaction between nitric acid (HNO3) and barium hydroxide (Ba(OH)2) can be represented by the following balanced chemical equation:

2HNO3 + Ba(OH)2 → Ba(NO3)2 + 2H2O

This is the complete ionic equation for the reaction:

2H+ + 2NO3- + Ba^2+ + 2OH- → Ba^2+ + 2NO3- + 2H2O

And this is the net ionic equation:

2H+ + 2OH- → 2H2O

Reaction 3: FeCl2 + AgNO3

The reaction between iron(II) chloride (FeCl2) and silver nitrate (AgNO3) can be represented by the following balanced chemical equation:

FeCl2 + 2AgNO3 → 2AgCl + Fe(NO3)2

This is the complete ionic equation for the reaction:

Fe^2+ + 2Cl- + 2Ag+ + 2NO3- → 2AgCl + Fe^2+ + 2NO3-

And this is the net ionic equation:

2Cl- + 2Ag+ → 2AgCl

Please note that the above equations are balanced and represent the stoichiometry of the reactions.
