Questions & Step-by-Step Solutions
In the reaction 2Fe + 3Cl2 → 2FeCl3, how many moles of Cl2 are needed to react with 4 moles of Fe?
Step 1: Look at the chemical equation: 2Fe + 3Cl2 → 2FeCl3.
Step 2: Identify the ratio of Fe to Cl2 from the equation. It shows that 2 moles of Fe react with 3 moles of Cl2.
Step 3: Determine how many moles of Cl2 are needed for 1 mole of Fe. Since 2 moles of Fe need 3 moles of Cl2, 1 mole of Fe needs 3/2 moles of Cl2.
Step 4: Calculate how many moles of Cl2 are needed for 4 moles of Fe. Multiply the amount of Cl2 needed for 1 mole of Fe by 4: (3/2) * 4 = 6 moles of Cl2.
Step 5: Conclude that 4 moles of Fe will require 6 moles of Cl2.
