Question

What happens when coal is burn in the presence of oxygen? Write chemical equation?

Answer 1

Answer:

If coal is heated in the presence of air,then coal burns to produce mainly carbon dioxide gas and no other useful products were obtained. It is a gaseous fuel which is obtained by the strong heating of coal in the absence of air during the processing of coal to get coke

Explanation:

C + O2 = CO2

Answer 2

Carbon dioxide and heat are generated when coal is burnt in the presence of oxygen.

- Coal is mainly made out carbon contents.

- So,the combustion of the coal is actually the combustion of carbon.

- During this combustion process,the carbon is chemically bonded with the atmospheric oxygen and forms carbon dioxide.

- Chemical reaction :

C + O2 = CO2 + ∆

(Generated heat during the combustion is denoted by the '∆',in the above chemical reaction)
