After the new NH_(3) molecule came on the right side, how many TOTAL Nitrogen atoms are on the right side? 8 2 4 6

To determine the total number of nitrogen atoms on the right side after the new $NH_{3}$ molecule comes on, we need to look at the chemical equation and see how many nitrogen atoms are present.<br /><br />Let's assume the chemical equation is:<br /><br />$N_{2} + 3H_{2} \rightarrow 2NH_{3}$<br /><br />In this equation, we can see that there are 2 nitrogen atoms on the left side (in $N_{2}$) and 2 nitrogen atoms on the right side (in $2NH_{3}$).<br /><br />Therefore, the total number of nitrogen atoms on the right side is 2.<br /><br />So, the correct answer is 2.
