What is the limiting reactant when 4.5 moles of aluminum react with 6.7 moles of oxygen gas? unbalanced equation: al + o2 → al2o3 show, or explain, all of your work along with the final answer.

Answer : The limiting reagent is, Aluminum (Al)

Explanation : Given,

Given moles of Al = 4.5 moles

Given moles of = 6.7 moles

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

From the given balanced reaction, we conclude that

As, 4 moles of react with 2 moles of

So, 4.5 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent because it limits the formation of product.

Hence the limiting reagent is, Aluminum (Al)
