Question

Balance the following chemical reactions and write the type of reaction also:
1: CHA[g] + O2(g) → CO2(g) + H2O()
Methane + Oxygen → Carbon Dioxide + Water
2. Al[s] + O2(g) → Al2O3 [s]
Aluminum + Oxygen → Aluminum Oxide
3. KCIO3[s] → KCI[s] + O2[g]
Potassium Chlorate → Potassium Chloride + Oxygen
4. Mg(s) + HCl(aq) → MgCl2(aq) + H2[g]
Magnesium + Hydrogen Chloride → Magnesium Chloride + Hydrogen
5. NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl[s]
Sodium Chloride + Silver Nitrate → Sodium Nitrate + Silver Chloride​

Answer 1

Hi there,

1) CH4 + 2O2 => CO2 + 2H2O , Combustion reaction

2) 4Al + 3O2=> 2Al2O3 , Combustion also = direct compination

3) 2KClO3=> 2KCl + 3O2 , thermal decomposition

4) Mg + 2HCl => MgCl2 + H2

Displacement = single deplacement

5) NaCl+ AgNO3 => AgCl + NaCl

Double displacement= precipitation
