The equation shows the reaction between ammonia (NH3) and oxygen (O2).

__NH3 + __O2 → __NO + __H2O< /p>

From left to right, which set of coefficients balances the equation to follow the law of conservation of mass?

A
4, 5, 4, 6

B
5, 4, 5, 4

C
5, 4, 4, 5

D
4, 6, 4, 5

The balanced equation for the reaction between ammonia (NH3) and oxygen (O2) should be:

4NH3 + 5O2 → 4NO + 6H2O

Therefore, the correct set of coefficients is A) 4, 5, 4, 6.
