Oxidation and reduction
Explanation:
2H₂S + SO₂ ---> 2H₂O + 3S
(a) Substance oxidised is Hydrogen, as oxygen gets added to hydrogen to form water.
(b) Substance reduced is SO2. Oxygen is removed to form Sulphur.
(c) Type of reaction is redox reaction, as both oxidation and reduction occur simultaneously during the reaction.
(d) The above reaction is exothermic reaction. An exothermic reaction is a chemical reaction that releases energy through light or heat.
