First, If 100.0 g of iron (III) oxide reacts with 40.00 g of aluminum to form aluminum oxide and iron, how many grams of aluminum oxide is made, and how much reactant remains? Next, How do you recognize a limiting reaction problem?
First, If 100.0 g of iron (III) oxide reacts with 40.00 g of aluminum to form aluminum oxide and iron, how many grams of aluminum oxide is made, and how much reactant remains?
Next, How do you recognize a limiting reaction problem?
Given : Mass of iron (III) oxide i.e Fe2O3 = 100.0 g
And mass of Aluminium i.e Al = 40.00 g
To recognize whether the problem is limiting reaction problem or not, always check for the reaction taking place and the given values.
If amount of multiple reactants are given, then it will always be a limiting reactant problem because in 95% + such questions, the amount of reactants are not given in reaction coefficient ratio.
So it is always advisable to identify the limiting reactant if the amount of multiple reactants are given in question.
