Question

Can you check my chemistry for me? Limiting reactants?

Answer 1

What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water?

Unbalanced equation: \[Al + H _{2}O \rightarrow Al _{2}O _{3} + H _{2}\]
Balanced Equation: \[2Al + 3H _{2}O \rightarrow Al _{2}O _{3} +3H _{2}\]
\[5.06 mol Al \times \frac{ 1molAl _{2}O _{3} }{ 2mol Al } = 2.08 mol Al\]
\[6.2 mol H _{2}O \times \frac{ 1molAl _{2}O _{3} }{ 3molH _{2}O } = 2.06 mol H _{2}O\]

Water is the limiting reactant.

Answer 2

Do you mean 5.6 moles of Al?
Anyway, water is the limiting reactant.

Answer 3

Yes, that is what I meant to type, sorry lol

Answer 4

But anyways, thank you!
