Question

5.29 Use the molecular art to write a balanced equation for the given reaction

I am totally confused about how I am supposed to do this/identify the molecules. Please help!

Answer 1

In the reactant side, there are 3 CH4 molecules and 9 Cl2 molecules.

The carbon atoms are black colored, Hydrogen atoms are grey and chlorine atoms are orange.

After reaction there becomes 3 CHCl3 molecules and 9 HCl molecules.

The total reaction is:-

$\fn_jvn \large 3CH_{4}+9Cl_{2} \rightarrow 3CHCl_{3} + 9}HCl$

The balanced chemical reaction is:-

$\fn_jvn \large CH_{4}+3Cl_{2} \rightarrow CHCl_{3} + 3HCl$
