Balance the following redox reactions by oxidation method.
(a) MnO4- (aq) + I-(aq) → Mno2 (s) +I2 (s) (in basic medium)
(b) MnO4-(aq) + SO2 (g) → Mn2+(aq) + HSO4- (aq) (in acidic solution
(C) H202 (aq) + Fe2+ (aq) → Fe3+ (aq) + H20 (l) (in acidic solution)
(d) Cr2O²-7+ SO2 (g) → Cr3+ (aq) +SO²-7 (aq) (in acidic solution)

Explanation:
Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.
