Question

___H2 + ___N2 → ___NH3 When the chemical equation in the figure is balanced, what would be the correct SUM of all of the coefficients?

Answer 1

Answer:

Sum of Coefficients = 3 + 1 + 2 = 6

Explanation:

$3H_{2} + 1N_{2}$ ↔ $2NH_{3}$

Answer 2

Answer:

6

Explanation:

H2 +N2-> NH3

in balanced form:

3H2+1N2- > 2NH3

so the sum of all the coefficient is 3 +2+1 = 6
