Question
Solid aluminum reacts with oxygen gas to form solid aluminum oxide. if 8.5 moles of aluminum reacts with excess oxygen gas, how many moles of aluminum oxide can be formed? Solid aluminum reacts with oxygen gas to form solid aluminum oxide. if 8.5 moles of aluminum reacts with excess oxygen gas, how many moles of aluminum oxide can be formed? Solid aluminum reacts with oxygen gas to form solid aluminum oxide. if 8.5 moles of aluminum reacts with excess oxygen gas, how many moles of aluminum oxide can be formed?Explanation / Answer
The balanced equation is
4Al (g) +3 O2 (g) --------------->2 Al2O3(s)
Thus 4 moles of Al on reaction with oxygen gives 2 moles of Al2O3
if 8.5 moles of Al reacts = 8.5x2 /4
= 4.25 moles of Al2 O3 is formed.
