Rusting Nails: Nails are made of the element iron. Iron has the atomic mass 55.8 g/mol. Nails are very important construction materials. However, when nails are exposed to the atmosphere, it undergoes a chemical reaction called rusting. When nails rust, they combine with oxygen gas in the air. Oxygen gas has a molar mass of 32.0 g/mol. The resulting substance is a flaky brown substance called iron(III) oxide, Fe203. The formula mass of iron(III) oxide is 159.7 g/mol. The balance chemical reaction for the rusting of nail is: 4 Fe(s) + 3 02(g) → 2 Fe203(s) 1. If 1.5 mole of iron rusts, how many moles of oxygen gas will react with it? Answer: 2. How many grams of iron(III) oxide are produced when 2 moles of oxygen gas reacted? Answer: 3. How many moles of iron rusted if 450 grams of iron(III) oxide was produced? Answer: 4. If 95.0 grams of iron rusted, how many grams of iron(III) oxide are produced? Answer: HIMod Mar 23, 2022 at 8:48 am
