Problem 55

The scenes below represent a chemical reaction between elements A (red) and B (green):
Which best represents the balanced equation for the reaction?
$\begin{array}{ll}{\text { (a) } 2 \mathrm{A}+2 \mathrm{B} \longrightarrow \mathrm{A}_{2}+\mathrm{B}_{2}} & {\text { (b) } \mathrm{A}_{2}+\mathrm{B}_{2} \longrightarrow 2 \mathrm{AB}} \\ {\text { (c) } \mathrm{B}_{2}+2 \mathrm{AB} \longrightarrow 2 \mathrm{B}_{2}+\mathrm{A}_{2}} & {\text { (d) } 4 \mathrm{A}_{2}+4 \mathrm{B}_{2} \longrightarrow 8 \mathrm{AB}}\end{array}$
