What are the chemical reactions of carbon? |
|
Answer» Solution :Elemental carbon undergoes no reaction at room temperature and limited number of reactions at elevated temperatures. But its compounds undergo large number of reactions even at room temperature. Oxidation - (Reaction with oxygen) Carbon combines with oxygen to form its oxides like carbon monoxide (CO) and carbon dioxide `(CO_(2))` with evolution of heat. Organic carbon compounds like hydrocarbon also undergo oxidation to form oxides and steam with evolution of heat and FLAME. This is otherwise CALLED Burning. `2C_((s))+O_(2(g))to2CO_((g))+"heat"` `C_((s))+O_(2(g))toCO_((g))+"heat"` Reaction with steam Carbon REACTS with steam to form carbon monoxide and hydrogen. This mixture is called water gas. `C_((s))+H_(2)O_((g))toCO_((g))+H_(2(g))` Reaction with sulphur With sulphur carbon forms its DISULPHIDE at high temperature. `C_((s))+S_((g))toCS_(2(g))` Reaction with metals At elevated temperatures, carbon reacts with some metals like iron, tungsten, Titanium, etc. to form their carbides. `W_((s))+C_((g))toWC_((s))` |
