In the balanced chemical equation for the formation of ammonia (NH3) from
nitrogen (N2) and hydrogen (H2), the sum of the coefficients is______
Please help!

Respuesta :

Answer:

4

Explanation:

first write down the balanced equation:

N2 + 3 H2 → 2 NH3

when there is no coefficient written, there is actually an "invisible" 1 coefficient. so the coefficient of nitrogen (N2) is 1.

coefficient of N2 is 1 and the coefficient of H2 is 3.

then sum coefficients!
