Coke amorphous form of carbon
WebJun 22, 2016 · We have four types of coal namely: Peat – Like coal which is about 60% carbon by mass Lignite – Which is a brown soft coal having about 67% carbon by mass Bituminous – Which we use every day at home. It contains about 88% by mass of carbon Anthracite – This is tough and hard, having about 94% of carbon by mass WebAt insufficient amount of Oxygen (O2), carbon forms CO (carbon monoxide), that is called incomplete combustion. 2 C (s) + O2 (g) → 2 CO (g) Reaction with water It doesn’t react with water under normal condition. But At high temperature, carbon will react, when water is blown through hot coke.
