Answer:
the third one
Explanation:
after balancing the rxn will be like this
4NH3+6NO->5N2+6H2O
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.
