Answer 2

a) Zn + N2 = Zn3N2

The given chemical equation represents the reaction between zinc (Zn) and nitrogen gas (N2) to form zinc nitride (Zn3N2). This is a synthesis reaction, also known as a combination reaction, where two or more substances combine to form a single compound.

The balanced chemical equation for this reaction is:

Zn + N2 → Zn3N2 [[1]]

b) B + F2 = IF3

The given chemical equation represents the reaction between boron (B) and fluorine gas (F2) to form boron trifluoride (IF3). This is also a synthesis reaction.

The balanced chemical equation for this reaction is:

B + F2 → IF3 [[2]]

c) Fe(OH)3 = Fe2O3 + H2O

The given chemical equation represents the decomposition of iron(III) hydroxide (Fe(OH)3) to form iron(III) oxide (Fe2O3) and water (H2O). This is a decomposition reaction, where a single compound breaks down into two or more simpler substances.

The balanced chemical equation for this reaction is:

2Fe(OH)3 → Fe2O3 + 3H2O [[3]]

d) Al + H2SO4 = Al2(SO4)3 + H2

The given chemical equation represents the reaction between aluminum (Al) and sulfuric acid (H2SO4) to form aluminum sulfate (Al2(SO4)3) and hydrogen gas (H2). This is a displacement reaction, where one element replaces another element in a compound.

The balanced chemical equation for this reaction is:

2Al + 3H2SO4 → Al2(SO4)3 + 3H2 [[4]]

e) H2O + P2O5 = H3PO4

The given chemical equation represents the reaction between water (H2O) and diphosphorus pentoxide (P2O5) to form phosphoric acid (H3PO4). This is a synthesis reaction.

The balanced chemical equation for this reaction is:

P2O5 + 3H2O → 2H3PO4 [[5]]

Please note that the balanced chemical equations provided above are based on the given reactions and may vary depending on the reaction conditions.
