Question

select the correct answer.
is this equation balanced and in the lowest form?
4nh₃→2n₂ + 6h₂
a. yes, because there are equal amounts of atoms of each element on both sides.
b. no, because the coefficients could be reduced to 2,1, and 3.
c. yes, because the coefficients are in their lowest whole number ratio.
d. no, because the coefficients could be reduced to 2, 2, and 4.

Explanation:

Step1: Check atom balance

For \(N\): Left side \(4\) (from \(4NH_3\)), right side \(2\times2 = 4\). For \(H\): Left side \(4\times3=12\), right side \(6\times2 = 12\). So the equation is balanced.

Step2: Check coefficient reduction

The coefficients \(4,2,6\) have a greatest - common - divisor of \(2\). Dividing each by \(2\) gives \(2NH_3
ightarrow N_2 + 3H_2\). So the original equation is not in the lowest form.

Answer:

B. No, because the coefficients could be reduced to 2,1, and 3.
