Answer 1

MgCO3 + 2HCl -> MgCl2 + CO2 + H2O
MgCO3 + 2H(+) + 2Cl(-) -> Mg(+2) + 2Cl(-) + CO2 + H2O
MgCO3 + 2H(+) -> Mg(+2) + CO2 + H2O

Ag2O + 2HNO3 -> 2AgNO3 + H2O
Ag2O + 2H(+) + 2NO3(-) -> 2Ag(+) + 2NO3(-) + H2O
Ag2O + 2H(+) -> 2Ag(+) + H2O

H3PO4 + NO -> реакция не идёт

2HCl + Fe(OH)2 -> FeCl2 + 2H2O
2H(+) + 2Cl(-) + Fe(OH)2 -> Fe(+2) + 2Cl(-) + 2H2O
2H(+) + Fe(OH)2 -> Fe(+2) + 2H2O

Hg + H2SO4 -> реакция не идёт

6HCl + 2Al -> 2AlCl3 + 3H2
6H(+) + 6Cl(-) + 2Al(0) -> 2Al(+3) + 6Cl(-) + 3H2(0)
6H(+) + 2Al(0) -> 2Al(+3) + 3H2(0)

In this reaction, silver oxide reacts with nitric acid to produce silver nitrate and water.

The ionic equation for this reaction can be written as:

2Ag+ + O^2- + 2H+ + 2NO3- → 2Ag+ + 2NO3- + H2O

The spectator ions in this reaction are silver ions (Ag+), which remain unchanged throughout the reaction.

c) H3PO4 + NO =

The reaction between phosphoric acid (H3PO4) and nitric oxide (NO) can be represented by the following balanced chemical equation:

H3PO4 + NO → HNO3 + H2O [[3]]

In this reaction, phosphoric acid reacts with nitric oxide to produce nitric acid and water.

The ionic equation for this reaction can be written as:

3H+ + PO4^3- + NO → NO3- + H2O

The spectator ions in this reaction are hydrogen ions (H+), which remain unchanged throughout the reaction.

г) HCl + Fe(OH)2 =

The reaction between hydrochloric acid (HCl) and iron(II) hydroxide (Fe(OH)2) can be represented by the following balanced chemical equation:

2HCl + Fe(OH)2 → FeCl2 + 2H2O [[4]]

In this reaction, hydrochloric acid reacts with iron(II) hydroxide to produce iron(II) chloride and water.

The ionic equation for this reaction can be written as:

2H+ + 2Cl- + Fe^2+ + 2OH- → Fe^2+ + 2Cl- + 2H2O

The spectator ions in this reaction are chloride ions (Cl-) and iron(II) ions (Fe^2+), which remain unchanged throughout the reaction.

д) Hg + H2SO4 =

The reaction between mercury (Hg) and sulfuric acid (H2SO4) can be represented by the following balanced chemical equation:

Hg + H2SO4 → HgSO4 + H2O + SO2 [[5]]

In this reaction, mercury reacts with sulfuric acid to produce mercury(II) sulfate, water, and sulfur dioxide.

The ionic equation for this reaction can be written as:

Hg + H+ + HSO4- → HgSO4 + H2O + SO2

The spectator ions in this reaction are hydrogen ions (H+), which remain unchanged throughout the reaction.

е) HCl + Al =

6HCl + 2Al → 2AlCl3 + 3H2 [[6]]

In this reaction, hydrochloric acid reacts with aluminum to produce aluminum chloride and hydrogen gas.

The ionic equation for this reaction can be written as:

6H+ + 6Cl- + 2Al → 2Al^3+ + 6Cl- + 3H2

The spectator ions in this reaction are chloride ions (Cl-), which remain unchanged throughout the reaction.

Please note that the above equations are balanced and represent the overall reaction. In some cases, additional steps or intermediate species may be involved in the reaction mechanism, but the provided equations represent the net reaction.
