nitrogen and hydrogen react to form ammonia, nh3. n2 + h2 → nh3 what is the correct balanced chemical reaction? 3n2 + 3h2 → nh3 n2 + 3h2 → 2nh3 2n2 + h2 → nh3 n2 + h2 → n2h2
Answer
Explanation:
Step1: Count nitrogen atoms
On the left - hand side of the unbalanced equation $\text{N}_2+\text{H}_2\rightarrow\text{NH}_3$, there are 2 nitrogen atoms in $\text{N}_2$. On the right - hand side, there is 1 nitrogen atom in $\text{NH}_3$. To balance nitrogen, we need 2 moles of $\text{NH}_3$.
Step2: Count hydrogen atoms
After putting a coefficient of 2 in front of $\text{NH}_3$, we have 6 hydrogen atoms on the right - hand side. On the left - hand side, $\text{H}_2$ has 2 hydrogen atoms. So we need 3 moles of $\text{H}_2$ to balance the hydrogen atoms.
Answer:
B. $\text{N}_2 + 3\text{H}_2\rightarrow2\text{NH}_3$
