Question

Name the following:
1. The product formed on oxidation of phosphorus.
2. The acid formed when the above product of oxidation of phosphorus, reacts with water.
3. The chemical name of rust.
4. The pollutant which combines with water vapour to give sulphuric acid a product of acid rain.
5. The gas required for both combustion & rusting.​

Answer 1

Answer:

1)Phosphorus pentoxide. Phosphorus acid. Hydrated iron (III) oxide.

2)phosphoric acid

3)iron oxide

4) Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids

5)oxygen(O2).

Answer 2

Answer:

1.Phosphorus pentoxide.

2.phosphoric acid.

3.iron oxide.

4.Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

5.The gas which is used as both rusting and burning is oxygen(O2).
