The number of electrons required to balance the following equation-
NO, + 4H+ +--- →2H,0 + NO are -
(1) 5
(2)4
(3)3how many electrons ​

Answer 1

Answer:

4 electrons required .

Explanation:

as LHS side net charge is +5 and in RHS side net charge is+1 since 4e^-1(or electrons) needed to balance this equation since answer is option (2).

Answer 2

4 electrons required to balance.

Explanation:

$NO_3 + 4H^+\rightarrow 2H_2O + NO$

Charge on right hand side = 0

Charge on left hand side = 4+

To balance the charge add the electrons to that side where positive charge is greater .

Number of electrons required to balance the reaction = 4 - 0 = 4
