Statement 1 is correct. Nylon was the first synthetic fibre made from chemicals. It is a wrinkle resistant fibre. Statement 2 is also correct. High grade polyethylene is used to make bulletproof material.

In an industry, TNT is produced in a three-step process. First, toluene is nitrated with a mixture of sulphuric and nitric acid to produce mononitrotoluene (MNT). The MNT is separated and then renitrated to dinitrotoluene (DNT). In the final step, the DNT is nitrated to trinitrotoluene (TNT) using an anhydrous mixture of nitric acid and oleum. Nitric acid is consumed by the manufacturing process, but the diluted sulphuric acid can be reconcentrated and reused. 

Asprin (commonly used as pain reliever) is basically acetylsalicyclic acid.

Nettle sting contains methanoic acid (formic acid). To neutralize its effect, some base should be applied on the affected area.

Statement 1 is incorrect. When steam is passed over red-hot coke, water gas is produced. Compressed natural gas (CNG) is natural gas under pressure. Statement 2 is correct. Potassium permanganate (pink solution) is an oxidizing agent so it is an antiseptic solution.

Chlorination is the process of adding chlorine in water to make it fit for human consumption as drinking water. Water which has been treated with chlorine is effective in preventing the spread of water-borne diseases.

Statement 1 is incorrect: Methane is known as marsh gas because it is formed by methanogenic organisms that can be found in marshy areas. Statement 2 is correct: Hydrogen sulphide and sulphur bacteria mostly smell like rotten eggs.

Statement 1 is correct. When things are at their most basic breaking down state, they tend to last longer. Such is the same for a rubber band, when a rubber band is stretched it causes its polymer chains to become very ordered and it expels thermal energy (heat) thus extending its life. Statement 2 is also correct. The thickening power of cellulose also allows for more air to be whipped into products like ice cream, or whipped topping.

The pearls are mainly composed of calcium and magnesium carbonates.

LPG (Liquefied Petroleum Gas) contains butane and propane.
