In the reaction h2co3 (aq) + 2nh3 (aq) = 2nh4^+ (aq) + co3 2- (aq), how many electrons are transferred? a. 1 b. 2 c. 3 d. 4 e. none of the above (this is not a redox reaction)

The electrons are transferred when the reaction is redox reaction. It means that there must be reduction and oxidation.

The given equation is

The oxidation number of each element remains the same before and after the reaction.

H = +1

C: +4

O: -2

N: -3

Thus this is simple acid base reaction and not redox

There is transfer of proton from bicarbonate to ammonia

this is not a redox reaction

an honest friend. a friend who cares about me, and wont use me. a friend that i can trust. not someone who is fake

mark this brainliest lol i need one more.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
