Question

A hydrocarbon burns in air to produce --------------------- and----------------.

• A. ${\mathrm{CO}}_2$
• B. Heat and water(H₂O)

Answer 1

Combustion: The process of a burning substance in the presence of air producing CO₂, hate, and light is called combustion.

It is a combustion reaction.

Example: $$\begin{gathered} \mathrm{Hydrocarbon}\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\stackrel{∆}{\to }{\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)+\mathrm{Heat} \\ \mathrm{Oxygen}\mathrm{Carbondioxide}\mathrm{water} \end{gathered}$$

Therefore a Hydrocarbon reacts with Oxygen to give Carbon dioxide, Water, and Heat
