88 MULTIPLE CHOICE Question 10 The chemical equation below shows the reaction that takes place when rust forms. How many moles of oxygen are required to make 2 moles of iron (III) ox- ide (Fe_(2)O_(3)) 4Fe_((s))+3O_(2(g))arrow 2Fe_(2)O_((s)) A 1 mole B 2 moles C 4 moles D 3 moles

## Step 1The given chemical equation is: This equation tells us that 4 moles of iron (Fe) react with 3 moles of oxygen (O2) to produce 2 moles of iron (III) oxide (Fe2O3).## Step 2We are asked to find out how many moles of oxygen are required to produce 2 moles of iron (III) oxide.## Step 3We can set up a proportion to solve this: ## Step 4Solving for x gives us:
