8 0

Answer:

Explanation:

Personal opinion/interpretation are usually firsthand explanation to a phenomenon or problem set. They are usually drawn from logical reasoning and deduction about some event. Most times, they are non-scientific in nature in that they are non-methodical and do not rely on the critical thinking precepts scientific studies are hinged on.

Verified observations are usually drawn from carefully planned experiments. From the results of the experiment, critical decisions can be made.

If you have 3.50 moles of hydrogen and 5.00 moles of nitrogen to produce ammonia, which element is the reactant in excess? 3H2 +
kicyunya [14]

Answer:

nitrogen

Explanation:

The stoichiometry of the reaction says that H_{2} and  N_{2} react 3:1 to form 2 moles of  NH_{3}, so, if you have 3,5 moles of H, which is equal to 1,75 moles of  H_{2}, and 5 moles of N, which are equal to 2,5 moles of  n_{2}. only\frac{1,75 moles of H2}{3}=0.583 moles of  N_{2}, will react, leaving <em>1.917 moles of </em> N_{2} <em>unreacted</em>, and forming 0.583*2=1.166 moles of  NH_{3}
