PLEASE HELP! 1. There are four stages in the conversion of sulphur into sulphuric acid.
Stage 1: Sulphur is burnt to make sulphur dioxide.
Stage 2: Sulphur dioxide is oxidised to sulphur trioxide (the Contact Process).
Stage 3: Sulphur trioxide is dissolved in sulphuric acid to form oleum.
Stage 4: Oleum is diluted with water to form concentrated sulphuric acid.
(a) State the catalyst and give the equation for stage 2 (the Contact Process).
[3]
(b) Calculate the mass of sulphur needed to make 196 kg of sulphuric acid.
[3]
(c) Give two uses of sulphuric acid.

(d) Describe what you would see and name the products formed when dilute sulphuric acid reacts
with magnesium carbonate.
