hope it helps mark it as brainlist if you are satisfied .

hey please yr mark it as brainlist, I helped you and you only like my answer, I am dis appointed

Answer 2

Explanation:

1.The gas produced when excess ammonia reacts with chlorine. A gas which turns acidified potassium dichromate clear green. The gas produced when copper reacts with concentrated nitric acid. The gas produced on reaction of dilute sulphuric acid with a metallic sulphide:

2.Caustic soda is the common name for sodium hydroxide. The chemical formula for this soda is NaOH. When aluminium is reacted with concentrated caustic soda, it forms a salt and releases gas.

3.When potassium sulphite is treated with dilute hydrochloric acid, sulphur dioxide gas is evolved along with potassium chloride and water.

4.Dilute Hydrochloric acid is added to Copper Carbonate. When dilute hydrochloric acid is added to copper carbonate, it decomposes to give copper chloride.

5.When dilute sulphuric acid is added to a mixture of iron fillings and sulphur powder heated to red hot followed by cooling, iron reacts with sulphur to form iron sulphide, FeS. FeS formed reacts with sulphuric acid to form ferrous sulphate and release hydrogendisulphide gas.
