The mass of molten iron produced when 1.50 kg of aluminium reacts with 25.0 mol of iron ( III ) oxide is to be calculated. Concept introduction: The redox reaction can be classified into three types depending upon the number of reactants and products as follows: 1. Combination redox reaction 2. Decomposition redox reaction 3. Displacement redox reactions Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product. A limiting reagent is the one that is completely consumed in a chemical reaction . The amount of product formed in any chemical reaction has to be in accordance with the limiting reagent of the reaction. The amount of product depends on the amount of limiting reagent since the product formation is not possible in the absence of it.

Interpretation Introduction

Interpretation:

The mass of molten iron produced when 1.50 kg of aluminium reacts with 25.0 mol of iron(III)oxide is to be calculated.

Concept introduction:

The redox reaction can be classified into three types depending upon the number of reactants and products as follows:

1. Combination redox reaction

2. Decomposition redox reaction

3. Displacement redox reactions

Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product.

A limiting reagent is the one that is completely consumed in a chemical reaction. The amount of product formed in any chemical reaction has to be in accordance with the limiting reagent of the reaction. The amount of product depends on the amount of limiting reagent since the product formation is not possible in the absence of it.
