5. Consider the following reaction: 2 MNCO3(s) + O2(g) → 2 MnO2 (s) +2 CO2 (g) a. Determine the oxidation numbers for each of the atoms in the above equation.

Identify which are being oxidized and which are being reduced. b. If 17.5 g of MNCO3 is reacted with excess oxygen at 298K and 1.00 atm, what volume (in L) ofCO2 (g) is produced?
