Thank youFor Q8 C2O4 has an overall charge of 2- since Oxygen will give - 8 charge you will have to +6 to make the overall charge to 2-,therefore each atom of C will have +3 charge and its oxidation as the the oxidation state changes from +3 to +4.

For Q18 you'll have to make equation of decomposition for each nitrate and use the total mass of gas obtained of No2 and O2 which is 108g and solve by mass ratios.

Could you plz explain about the mass ratios and how you are calculating themm
