1
Combustion Reaction A substance combines with oxygen, releasing a large amount of energy in the form of light and heat Hydrocarbons combustion ALWAYS produces carbon dioxide and water C3H8 (g) + 5O2 (g) →3CO2 (g) +4H2O (g) (heat and light)
2
Burning Zinc Powder
3
Classify each of the following reactions in as many ways as possible
4NH3 (g) + 5O2 (g) → 4NO(g) + 6H2O (g) combustion S8 (s) + 8O2 (g) → 8SO2 (g) combustion, synthesis 2Al(s) + 3Cl2 (g) →2AlCl3 (s) synthesis 2AlN (s) →2Al (s) + N2 (g) decomposition
4
Classify each of the following reactions in as many ways as possible
BaCl2 (aq) + Na2SO4 (aq) → BaSO4 (s) + 2NaCl (aq) double, Precipitation KOH (aq) + HCl (aq) → H2O (l) + KCl (aq) double 2H2O (l) →2H2 (g) + O2 (g) decomposition
