Question

question 11 (multiple choice worth 5 points) (03.03r mc) what is the formula for manganese (iv) oxide? mno4 mn4o mno2 mn2o

Explanation:

Manganese (IV) has a +4 oxidation state. Oxygen has a -2 oxidation state. To form a neutral compound, for every manganese ion with a +4 charge, we need two oxygen ions with -2 charges each. So the formula is $MnO_2$.
