Answer 2

Reaction 1: Cu(OH)2CO3 = CuO + CO2 + H2O

The given reaction is the decomposition of copper(II) carbonate. Copper(II) hydroxide carbonate decomposes to form copper(II) oxide, carbon dioxide, and water.

The balanced equation for this reaction is:

Cu(OH)2CO3 → CuO + CO2 + H2O

Reaction 2: Fe + Cl2 = FeCl3

The given reaction is the combination of iron and chlorine gas to form iron(III) chloride.

The balanced equation for this reaction is:

Fe + Cl2 → FeCl3

Reaction 3: NaOH + H2SO4 = Na2SO4 + H2O

The given reaction is the neutralization of sodium hydroxide and sulfuric acid to form sodium sulfate and water.

The balanced equation for this reaction is:

2NaOH + H2SO4 → Na2SO4 + 2H2O

Reaction 4: CaO + P2O5 = Ca3(PO4)2

The given reaction is the combination of calcium oxide and diphosphorus pentoxide to form calcium phosphate.

The balanced equation for this reaction is:

3CaO + P2O5 → Ca3(PO4)2

Reaction 5: H2SO4 + HCl = H2 + Al2(SO4)3

The given reaction is the displacement reaction between sulfuric acid and hydrochloric acid with aluminum to form hydrogen gas and aluminum sulfate.

The balanced equation for this reaction is:

3H2SO4 + 6HCl + 2Al → 3H2 + 2Al2(SO4)3

Reaction 6: Zn + FeCl3 = ZnCl2 + Fe

The given reaction is the displacement reaction between zinc and iron(III) chloride to form zinc chloride and iron.

The balanced equation for this reaction is:

Zn + 2FeCl3 → ZnCl2 + 2Fe Please note that the sources provided do not contain specific information about the reactions mentioned. The balanced equations provided are based on general knowledge of chemical reactions.
