Question

balance of atoms quick check
it takes 1 molecule of nitrogen and 3 molecules of hydrogen to produce 2 molecules of ammonia using the following formula:
1n₂ + 3h₂ → 2nh₃
identify which combination of molecules will produce ammonia with no leftovers?
(1 point)
2n₂ and 6h₂
4n₂ and 4h₂
8n₂ and 4h₂
5n₂ and 6h₂

Explanation:

Step1: Analyze reaction ratio

The reaction $N_2 + 3H_2
ightarrow2NH_3$ has a 1:3 ratio of $N_2$ to $H_2$.

Step2: Check each option

For $2N_2$ and $6H_2$, the ratio of $N_2$ to $H_2$ is $\frac{2}{6}=\frac{1}{3}$, which matches the reaction ratio. For $4N_2$ and $4H_2$, $\frac{4}{4} = 1
eq\frac{1}{3}$. For $8N_2$ and $4H_2$, $\frac{8}{4}=2
eq\frac{1}{3}$. For $5N_2$ and $6H_2$, $\frac{5}{6}
eq\frac{1}{3}$.

Answer:

$2N_2$ and $6H_2$
