Answer 1

4HI+2NO2 -> 2NO + 2I2 +2H2O

 

HI + NO2    ->

+-     +4 -4    +2 -2  0

 

                                                                        

 N +2 e - > N+2 I  4  I2

 O - 2 e ->  O-2  I      I2

Answer 2

Balancing the Chemical Equation: HI + NO2 = NO + I2 + H2O

To balance the chemical equation HI + NO2 = NO + I2 + H2O using the method of electronic balancing, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The given equation is: HI + NO2 = NO + I2 + H2O

Let's start by counting the number of atoms for each element on both sides of the equation:

On the left side: - Hydrogen (H): 1 atom from HI - Iodine (I): 1 atom from HI - Nitrogen (N): 1 atom from NO2 - Oxygen (O): 2 atoms from NO2

On the right side: - Nitrogen (N): 1 atom from NO - Iodine (I): 2 atoms from I2 - Hydrogen (H): 2 atoms from H2O - Oxygen (O): 1 atom from H2O

To balance the equation, we need to adjust the coefficients in front of the compounds. Here's the balanced equation:

2 HI + NO2 = 2 NO + I2 + H2O

Now, let's count the number of atoms for each element on both sides of the balanced equation:

On the left side: - Hydrogen (H): 4 atoms from 2 HI - Iodine (I): 2 atoms from 2 HI - Nitrogen (N): 2 atoms from NO2 - Oxygen (O): 4 atoms from 2 NO2

On the right side: - Nitrogen (N): 2 atoms from 2 NO - Iodine (I): 2 atoms from I2 - Hydrogen (H): 2 atoms from H2O - Oxygen (O): 2 atoms from H2O

Now, the number of atoms for each element is balanced on both sides of the equation.

Therefore, the balanced equation using the method of electronic balancing is:

2 HI + NO2 = 2 NO + I2 + H2O
