Iron is the most widely used of all metals, with its high strength and low cost making it ideal for structural components in buildings and machinery. However, it is not indefinitely stable - over time it reacts with oxygen in the air, forming rust - iron(III) oxide - according to the equation below. Suppose you have an iron nail, originally with a mass of 2.213 g. that begins to rust. If its new mass is 2.255 g, what mass of iron(III) oxide is now present in the nail? 4 Fe (s) + 3 O2 (g) --> 2 Fe2O3 (s) a. 0.042 g b. 0.060 g c. 0.14 g d. 0.21 g
