Concept explainers
Interpretation:
The moles of iron (III) oxide that are needed to produce
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amount of substances in a balanced
Following are the steps to determine the moles of a chemical substance when the moles of another chemical substance present in the chemical reaction are given,
Step 1: Write the names and molecular formulas of the substances involved in the chemical reaction.
Step 2: Write the balanced chemical equation by using
Step 3: Determine the molar ratio from the balanced chemical reaction between the chemical substance whose amount is given and the chemical substance whose amount is to be calculated.
Step 4: Use the molar ratio and the given amount to calculate the unknown amount of the other substance.
