what does H2O + SO2 equal? sulpheric acid (symbol??)and what??

Answer 1

Actually, its not sulfuric acid.
SO2 dissolves in water to form sulfurous acid, H2SO3.
To produce sulfuric acid, the SO2 has to be oxidized to SO3.
or H2SO3 must be mixed with oxidizing agent.
CONTACT PROCESS:

(1) S(s) + O2(g) → SO2(g)
This is then oxidized to sulfur Trixie using oxygen in the presence of a vanadium(V) oxide catalyst.

(2) 2 SO2 + O2(g) → 2 SO3(g) (in presence of V2O5)
Finally the sulfur trioxide is treated with water (usually as 97-98% H2SO4 containing 2-3% water) to produce 98-99% sulfuric acid.

(3) SO3(g) + H2O(l) → H2SO4(l)
Also,
SO2 + H2O → H2SO3

Answer 2

No. The SO2 dissolves in water to form sulfurous acid, H2SO3. To produce sulfuric acid, the SO2 has to be oxidized to SO3.
