As the group is descending. The ionisation energy decreases, hence it becomes less difficult to form the ions. With the…
Ionization energy is the energy needed to remove the outermost electron from an atom/gaseous atom to form an ion/gaseous ion…
Properties that show a gradual gradation down the group. 1. Reactions with cold water become increasingly more vigorous. 2. The…
Solution I will pass the hydrocarbon into bromine/ bromine water which is purple in colour. If the bromine becomes decolourised,…
Solution Unsaturation is a term/phenomenon used in describing a molecule that contains a multiply (double/triple) bond.
Solution CH4 + 2O2 → 2H2O + CO2 2C2H2 + 5O2 → 4CO2 + 2H2O
Solution (i) CH3COONa(s) + NaOH(aq) → Na2CO3(s) + CH4(g) (ii) CaC2(s) +2H2O (l) → Ca(OH)2(aq) + C2H2(g)
