<u>Answer:</u> The net chemical equation is given below.
<u>Explanation:</u>
To determine the net chemical equation, we will look into the intermediate steps:
<u>Step 1:</u> Formation of ammonia from hydrogen and nitrogen gas.
......(1)
<u>Step 2:</u> Formation of nitric acid from ammonia and oxygen gas.
.....(2)
The net chemical equation for the formation of nitric acid from hydrogen gas, nitrogen gas and oxygen gas follows by adding both the equations, we get:
By Stoichiometry of the reaction:
1 mole of hydrogen gas reacts with 2 moles of oxygen gas and 3 moles of hydrogen gas to produce 1 mole of nitric acid, 1 mole of water and 1 mole of ammonia.
Hence, the net chemical equation is given below.

Answer:
a. The apparatus required to purify gypsum sample are: Bunsen burner, beaker, Filter Funnel, stirring rod, the filter paper.
b. Gypsum is a sulfate mineral that is made up of calcium sulfate dihydrate. Step-by-step instruction to purify gypsum sample is as follows:
1. Add water to the gypsum sample in a beaker.
2. Use the stirring rod to mix the mixture well.
3. Filter off the excess solid from the mixture using the filter paper and filter funnel.
4. Put the filtered mixture over the bunsen burner and evaporate the excess water from the mixture.
5. Allow the hot liquid to cool down and filter it again through the filter paper to get the pure gypsum.
