Burning pyrites ore gives out A. Carbon dioxide gas B. Sulphur dioxide gas C. Nitrogen dioxide gas D. Nitric oxide gas

Carbon dioxide gas
Sulphur dioxide gas
Nitrogen dioxide gas
Nitric oxide gas

The correct answer is B. Sulphur dioxide gas.

Pyrites ore is a mineral that is composed of iron sulfide. When pyrites ore is burned, it reacts with oxygen in the air to form sulfur dioxide gas. Sulfur dioxide gas is a colorless, odorless gas that is toxic to humans and animals. It can cause respiratory problems, such as asthma and bronchitis. It can also cause acid rain.

Carbon dioxide gas is a colorless, odorless gas that is produced when organic matter is burned. It is also a greenhouse gas that contributes to climate change.

Nitrogen dioxide gas is

a reddish-brown gas that is produced when nitrogen and oxygen react in the presence of heat. It is a toxic gas that can cause respiratory problems.

Nitric oxide gas is a colorless, odorless gas that is produced when nitrogen and oxygen react in the presence of heat. It is a vasodilator that can help to improve blood flow.

In conclusion, the correct answer is B. Sulphur dioxide gas.
