Question

If we burn graphite residue will be left or no residue will be left or it will not burn or it will change into diamond

Answer 1

Answer:

Graphite is non flammable but can be burnt only in high temperatures.

Graphite needs around 400 degrees to get burnt.

It reduces when combined with air. it acts as a reducing agent.

It acts as an explosive when combines with air and dust.

And residue is left which is black in colour and non toxic.

Answer 2

Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2. When the air or oxygen supply is restricted, incomplete combustion to carbon monoxide, CO, occurs. 2C(s) + O2(g) → 2CO(g)

We will burn graphite in the presence of oxygen and carbon di oxide gas will formed as a product without any residue.It will stop burning due to more amount of carbon di oxide.
