Question

What happens when a mixture of acetylene and oxygen is burnt. Give a balanced chemical equation and write the name of the products and reactants.

Answer 1

Combustion is a chemical reaction that produces heat and is frequently accompanied by the release of energy.

Combustion usually involves the addition of Oxygen $\left(\mathrm{O}\right)$.

When a mixture of Acetylene $(\mathrm{HC}\equiv \mathrm{CH})$ and Oxygen is burned, Carbon dioxide $\left({\mathrm{CO}}_2\right)$ gas and heat energy is produced.

The balanced chemical equation of the combustion reaction of Acetylene is written as:

$$\begin{gathered} 2\mathrm{HC}\equiv \mathrm{CH}+5{\mathrm{O}}_2\to 4{\mathrm{CO}}_2+2{\mathrm{H}}_2\mathrm{O}+\mathrm{Heat} \\ \left(\mathrm{Acetylene}\right)\left(\mathrm{Oxygen}\right)(\mathrm{Carbon}(\mathrm{Water}) \\ \mathrm{dioxide}) \end{gathered}$$

The reactant present in the chemical equation is Acetylene. The product formed in the chemical equation is Carbon dioxide and water and heat is evolved.
