Pregunta: Equilibra la ecuación: PhCH 3 + KMnO 4 + H 2 SO 4 -> PhCOOH + K 2 SO 4 + MnSO 4 + H 2 O

We can balance the chemical equation

$\mathrm{P}\mathrm{h}\mathrm{C}{\mathrm{H}}_3+\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4+{\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4\to \mathrm{P}\mathrm{h}\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}+{\mathrm{K}}_2\mathrm{S}{\mathrm{O}}_4+\mathrm{M}\mathrm{n}\mathrm{S}{\mathrm{O}}_4+{\mathrm{H}}_2\mathrm{O}$ by algebraic method.

For that first give each compound a letter...
