In redox questions do I first balance normally and then find n factor of each compound/element like this for example?

Uhhhhhh 💀 sorry for 2 pings it told interaction failed
and i clicked it again and welp

its ok

N factor is the no of electron moles required to be transferred for oxidation/reduction for a species, you can find it without balancing
Notice the oxidation state of Mg changed from 0 to +2 therefore two mole of electrons were transferred per mole of Mg hence the n factor is 2 in case of Mg

ik but shd i first balance it normally

Good evening sir, thank you sir but my q is different, im asking shd I first balance normally that is for eg Mg + O2----> MgO
where i balance it by doing 2Mg + O2 ----> 2MgO
like that shd i normally balance it first and then find n factor? or am I doing something wrong

in case of this reaction you do whatever you think is easier to do
but if you have a redox reaction it is better to split into ox red halves
here, doing so overcomplicates a simple setup
redox here would be
Mg -> Mg 2+
O2 -> O2-
then balance out number of atoms, followed by charge
you could just balance the equation in a fraction of all this :)

in this case as well, there is no chagne in oxidation number that is heavy. sure, Mg is going to Mg 2+ and H+ is going to H
but just putting a 2 in a couple of places balances this :)

its a redox reaction right

its a redox reaction right
yep
the 'balancing normally' if you think it is easy to do, go for it. if it seems complicated, go the balancing of half reaction way!

Im getting more confused now.
What i meant was first shd I balance it normally and then proceed with the other
dawn scaffold
now I get what the problem was, the q has a h2O in it.. ;-; sorry my bad
it shd have been NO2 + H2O not just H2
dawn scaffold
no i mean the q shs have Mg + HNO3 ----> NO2+ H20 + Mg(NO3)2

We good?
