Multiple Choice 10 points N_(2)+3H_(2)arrow 2NH_(3) How many moles of hydrogen are needed to react with 2 moles of nitrogen? 3 6 1 2

The balanced chemical equation for the reaction between nitrogen and hydrogen to form ammonia is:<br /><br />$N_{2}+3H_{2}\rightarrow 2NH_{3}$<br /><br />From the equation, we can see that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. Therefore, if we have 2 moles of nitrogen, we need 2 x 3 = 6 moles of hydrogen to react completely.<br /><br />So, the correct answer is 6.
