When we expose iron constructions to water and oxygen, they become rusty. This chemical reaction, called corrosion, takes place in multiple steps and has multiple products which are all called rust. The (unbalanced) equation below shows the overall reaction for the synthesis of one type of rust is? An atom of iron (\ce{Fe})(Fe) is about 1.751.75 times heavier than a molecule of oxygen (\ce{O2}).(OX2). For each \SI{100}{\gram}100 g of \ce{Fe},Fe, approximately how many grams of \ce{O2}OX2 participate in the reaction above?
