Hey i need some help :)) (no diagram or explanation needed)

QUESTION 6 For the reaction below, determine the stoichiometric coefficient on water in the balanced redox reaction in basic solution. In compounds, the oxidation state of O is 2". Assume X is a nonmetal and that M is a metal that can have multiple oxidation states. This question is not multiple choice, you will input the integer answer to this question. MO42- (aq) + X(aq) →XO 4 (aq) + MO 2¯ (aq) ll answers
