Answer: 67.2 moles
Explanation:
According to the given balanced equation, 2 moles of acetylene combine with 5 moles of oxygen
to produce 4 moles of carbon dioxide
.
Thus if 2 moles of acetylene combine with = 5 moles of oxygen
35 moles of acetylene combine with=
moles of oxygen
But as only 84 moles of oxygen are available, acetylene is not a limiting reagent.
5 moles of oxygen reacts with = 2 moles of acetylene
84 moles of oxygen reacts with=
moles of acetylene
Thus Oxygen is the limiting reagent as it limits the formation of products. Acetylene is excess reagent as it is present in excess.
2 moles of acetylene produce= 4 moles of carbon dioxide
.
33.6 moles of acetylene produce=
moles of of carbon dioxide
.
