Answer 2

1. Al + O2 → ?

The reaction between aluminum (Al) and oxygen (O2) is a combination reaction, also known as a synthesis reaction. The product of this reaction is aluminum oxide (Al2O3). The balanced equation for this reaction is:

2 Al + 3 O2 → 2 Al2O3 [[1]]

2. Fe + H2O → Fe3O4 + H2

The reaction between iron (Fe) and water (H2O) is a redox reaction. Iron reacts with water to form iron(II) hydroxide (Fe(OH)2), which then oxidizes to form iron(III) oxide (Fe3O4) and hydrogen gas (H2). The balanced equation for this reaction is:

3 Fe + 4 H2O → Fe3O4 + 4 H2 [[2]]

3. AlPO4 → Al2O3 + P2O5

The reaction involving aluminum phosphate (AlPO4) is a decomposition reaction. Aluminum phosphate decomposes to form aluminum oxide (Al2O3) and phosphorus pentoxide (P2O5). The balanced equation for this reaction is:

2 AlPO4 → Al2O3 + P2O5 [[3]]

4. Ca + O2 → ?

The reaction between calcium (Ca) and oxygen (O2) is a combination reaction. The product of this reaction is calcium oxide (CaO). The balanced equation for this reaction is:

2 Ca + O2 → 2 CaO [[4]]

5. Al(OH)3 → Al2O3 + H2O

The reaction involving aluminum hydroxide (Al(OH)3) is a decomposition reaction. Aluminum hydroxide decomposes to form aluminum oxide (Al2O3) and water (H2O). The balanced equation for this reaction is:

2 Al(OH)3 → Al2O3 + 3 H2O [[5]]

6. FeCl2 + Cl2 → FeCl3

The reaction between iron(II) chloride (FeCl2) and chlorine gas (Cl2) is a redox reaction. Iron(II) chloride reacts with chlorine gas to form iron(III) chloride (FeCl3). The balanced equation for this reaction is:

2 FeCl2 + Cl2 → 2 FeCl3 [[6]]

7. Mg(OH)2 → ?

The reaction involving magnesium hydroxide (Mg(OH)2) is a decomposition reaction. Magnesium hydroxide decomposes to form magnesium oxide (MgO) and water (H2O). The balanced equation for this reaction is:

Mg(OH)2 → MgO + H2O [[7]]

8. Al + H2SO4 → Al2(SO4)3 + H2

The reaction between aluminum (Al) and sulfuric acid (H2SO4) is a redox reaction. Aluminum reacts with sulfuric acid to form aluminum sulfate (Al2(SO4)3) and hydrogen gas (H2). The balanced equation for this reaction is:

2 Al + 3 H2SO4 → Al2(SO4)3 + 3 H2 [[8]]

9. FeCl3 + NaOH → Fe(OH)3 + NaCl

The reaction between iron(III) chloride (FeCl3) and sodium hydroxide (NaOH) is a double displacement reaction. Iron(III) chloride reacts with sodium hydroxide to form iron(III) hydroxide (Fe(OH)3) and sodium chloride (NaCl). The balanced equation for this reaction is:

FeCl3 + 3 NaOH → Fe(OH)3 + 3 NaCl [[9]]

10. N2 + ? → NH3

The reaction between nitrogen gas (N2) and hydrogen gas (H2) is a combination reaction. The product of this reaction is ammonia (NH3). The balanced equation for this reaction is:

N2 + 3 H2 → 2 NH3 [[10]]
