How many moles of mg are consumed when 0.34 moles oxygen gas completely reacts?

0.34 moles of oxygen consumed 0.68 moles of magnesium

Explanation:

Given data:

Moles of magnesium = ?

Moles of oxygen = 0.34 mol

Chemical equation:

2Mg + O₂  → 2MgO

Now we will compare the moles of oxygen and magnesium:

                 O₂          :        Mg

                   1           :         2

                0.34       :         2×0.34 = 0.68 mol

Thus 0.34 moles of oxygen consumed 0.68 moles of magnesium.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
