C + HNO3 = CO2 + NO2 + H2O oxidation, reduction and balancing
C + 4 HNO3 = CO2 + 4 NO2 + 2 H2O
You need to make it clear as to what you want. Also it helps if you explain exactly what you don't understand.
@ DrBoB222 I would like to know how does the number of this oxidation reaction
@ DrBoB222 balancing by reducing oxide
You explanation still doesn't make sense to me. reducing oxide?
number of this oxidation reaction?
