Question

Equations that involves when sulphur is heated in the absence of air

Answer 1

Answer:

Heating sulfur is the start of the making of sulphuric acid (H2SO4).

The reaction is this: +2=2

S+O2=SO2

Next step is exposing it to a catalyst, to make SO3. Then very concentrated sulphuric acid is poured over the gas and it reacts with water to make nearly pure H2SO4.
