Metal + oxygen
Metal + oxygen –> Metal oxide
Metal + water
Metal + water –> Metal hydroxide + hydrogen
Thermal decomposition of carbonates
Metal carbonate –> Metal oxide + Carbon dioxide
Metal + Acid
Metal + Acid –> Salt + Hydrogen
Metal oxide + Acid
Metal oxide + Acid —> Salt + Water
Test for positive ions
Salt (aq) + Sodium hydroxide(aq) –> Metal hydroxide(s) + Sodium non-metal Ionic: Metal+ (aq) + Hydroxide- (aq) –> Metal hydroxide (s)
Test for halides
Metal halide(aq) + Silver nitrate(aq) –> Silver halide(s) + Metal nitrate(aq) Ionic: Halide- (aq) + Silver+ (aq) –> Silver halide (s)
Hydrocarbon Complete combustion
Hydrocarbon + oxygen –> Carbon dioxide + Water
Hydrocarbon Incomplete combustion
Hydrocarbon + oxygen –> Carbon monoxide + Water
Alkene Addition
Example: C2H4 + Br2 –>C2H4Br2
Aklane Substitution
Example: CH4 + Br2 –> CH3Br + HBr
Test for sulphates
Barium Chloride(aq) + Metal sulphate(aq) –> Barium Sulphate(s) + Chloride Salt(aq) BaCl2 + Metal SO4(aq) –> BaSO4(s) + Metal Cl (aq) Ba+2(aq) + SO4-2(aq) –> BaSO4(s)
Test for carbonates
Hydrochloric acid (aq) + Metal Carbonate(aq) –> Metal Chloride (aq) + Water (l) + CO2(g) HCl(aq) + Metal CO3(aq) –> Metal Cl(aq) + H2O(l) + CO2(g) 2H+ (aq) + CO3 -2 (aq) –> H2O (l) + CO2(g)
Test for water
Copper(II) Sulphate (s) + Water (l) –> Hydrated Copper(II) Sulphate (s) CuSO4(s) + 5H2O(l) –> CuSO4·5H2O(s)
Regular combustion
Element + Oxygen —> Element oxide
