# Gaseous nitrogen and gaseous hydrogen react to form ammonia according to the balanced equation below.

\[ \text{N}_2\text{(g)} + 3\text{H}_2\text{(g)} \rightarrow 2\text{NH}_3\text{(g)} \]

Nitrogen gas and hydrogen gas are placed in a rigid container, as shown in the particulate representation. Assuming the reaction proceeds to completion, which of the following diagrams best represents the contents of the container after the reaction?

Gaseous nitrogen and gaseous hydrogen react to form ammonia according to the balanced equation below.

\[ \text{N}_2\text{(g)} + 3\text{H}_2\text{(g)} \rightarrow 2\text{NH}_3\text{(g)} \]

Nitrogen gas and hydrogen gas are placed in a rigid container, as shown in the particulate representation. Assuming the reaction proceeds to completion, which of the following diagrams best represents the contents of the container after the reaction?

![A legend at the top maps: large filled circle = \(\text{N}\) atom; small open circle = \(\text{H}\) atom. Below the legend, a single square container represents the initial gas mixture. Inside the container, there are exactly \(3\) molecules of \(\text{N}_2\) and exactly \(6\) molecules of \(\text{H}_2\) evenly dispersed. Each \(\text{N}_2\) molecule consists of two touching large filled circles. Each \(\text{H}_2\) molecule consists of two touching small open circles. No individual particles have text labels. No other particles, bonds, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787299947-wBnDUn.jpg)
