2. The name iron (ll) indicates that a compound contains___ Iron ions with a 2+ charge
3. Alkali metals, alkaline earth metals, and aluminum all form ions with positive charges equal to___ The group number
4. In the name carbon dioxide, the prefix of the second word indicates that molecule of carbon dioxide contains___Two oxygen atoms
Explanation:
Answer: 67.2 moles
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 .
