Question

For the reaction NH3 + NO → N2 + H2O, identify the reactants, products, and their coefficients once the equation is balanced. (3 points)
Group of answer choices

Reactants: 2NH3 and 2NO; products: 2N2 and 3H2O

Products: 2NH3 and 3NO; reactants: 2N2 and 3H2O

Reactants: 4NH3 and 6NO; products: 5N2 and 6H2O

Products: 4NH3 and 2NO; reactants: 3N2 and 6H2O

Answer 1

Answer:

the third one

Explanation:

after balancing the rxn will be like this

4NH3+6NO->5N2+6H2O

Answer 2

Answer:

Reactants: 4NH3 and 6NO; products: 5N2 and 6H2O .

Explanation:

Reactants are the substances before reaction.  NH3 and NO. So, the answer should be 1 or 3.

NH3 +NO ---> N2 + H2O

Now we can check the coefficients.

1) 2NH3 + 2NO ---> 2N2 + 3H2O

Before reaction: N - 4, H - 6, O -2

After reaction : N -4 , H -6 , O -3

Wrong.

3) 4NH3 +6NO ---> 5N2 +6 H2O

Before reaction: N - 10, H - 12, O - 6

After reaction : N - 10 , H -12 , O - 6

Correct.
