Question

what is the chemical equation for incomplete combustion of acetylene and oxygen.

Answer 1

There are two ways of this process:

$$\begin{array}{l} 3 \mathrm{C}_{2} \mathrm{H}_{2} + 5 \mathrm{O}_{2} \rightarrow \mathrm{C} + 3 \mathrm{CO} + 2 \mathrm{CO}_{2} + 3 \mathrm{H}_{2} \mathrm{O} \\ 3 \mathrm{C}_{2} \mathrm{H}_{2} + 4 \mathrm{O}_{2} \rightarrow 2 \mathrm{C} + 3 \mathrm{CO} + \mathrm{CO}_{2} + 3 \mathrm{H}_{2} \mathrm{O} \\ \end{array}$$

Incomplete combustion of acetylene and oxygen gives carbon and carbon mono and dioxides, water is one of the products too.
