Answer: 6.38 moles of
are needed to react with 2.55 mol of 
Explanation:
The balanced chemical reaction for the combustion of ethyne is:

According to stoichiometry:
2 moles of
require = 5 moles of 
Thus 2.55 mol of
require =
moles of 
Thus 6.38 moles of
are needed to react with 2.55 mol of 
One benefit of this is that the weaknesses of some of their plans are covered by better plans. Another is that if the final plan doesn’t result, there are already many other ideas to go off of. A final benefit is that if the overall plan does work, it can still be easily improvised. Hope this helps! After all, this question is more opinion based.
Magnalium: Magnesium and Aluminum
