The vanadium salt, $VOS{O_4}$, is soluble in water and reacts readily with powdered manganese in
dilute sulfuric acid.
The equation for the reaction is shown.
$Mn\left( s \right) + 2VOS{O_4}\left( {aq} \right) + 2{H_2}S{O_4}\left( {aq} \right) \to {V_2}{\left( {S{O_4}} \right)_3}\left( {aq} \right) + MnS{O_4}\left( {aq} \right) + 2{H_2}O\left( l \right)$
Which statement about this reaction is correct?
