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

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

the answer is either b or c
