Question

 What gas is formed when carbon burns in limited air or oxygen? Write the balanced chemical equation for this reaction.

Answer 1

When carbon burns in the air, it reacts with the oxygen present in the air to form Carbon dioxide, and a large amount of heat and some light are released.
It is an example of a combustion reaction.
C_(s) + O_2(g) → CO_2(g) + heat + light

Answer 2

In limited air it is carbon ii oxide  the equation is 
C(s)+O(g)-CO(g)

Answer 3

Carbon (ii) oxide
C(s) +O(g) - - - CO(g)
