- word equation= sulphur + water--> sulphur dioxide
-symbol equation= S(l) + O2(g) → SO2(g)
- SULPHUR DIOXIDE SHOULD NOT BE RELEASED INTO THE ATMOSPHERE AS IT CONTRIBUTES DO LOCAL ACID RAIN.]]> 2020-12-10 14:05:13 UTC https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006128816 STAGE 2 (sulphur dioxide reacts with oxygen to form sulphur trioxide): mia_ziemska https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006207919 - word equation= sulphur dioxide + oxygen --> sulphur trioxide
- symbol equation= SO2+O2 --> SO3]]> 2020-12-10 14:21:58 UTC https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006207919 STAGE 3 (sulphur trioxide reacts with concentrated sulphuric acid to form oleum): mia_ziemska https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006243001 - sulphur trioxide is dissolved in sulphuric acid to create oleum. 
-The sulphur trioxide cannot be mixed with water because the reaction is very exothermic, so mixing it with water would release a mist of sulphuric acid that would escape into the air. 
- Instead, the sulphur trioxide is first dissolved in concentrated sulphuric acid: 
 - word equation= sulphur trioxide+ sulphuric acid --> oleum
symbol equation= SO3 + H2SO4 → H2S2O7

-word equation= oleum + water --> sulphuric acid
- symbol equation= H2S2O7 + H2O → 2H2SO4]]> 2020-12-10 14:36:33 UTC https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006279239 USES OF SULPHURIC ACID: mia_ziemska https://padlet.com/mia_ziemska/2ukl4n8ko728cwoh/wish/1006338103
