When iron is left unprotected, such as a nail exposed to the elements, it will develop a red-brown rust coating that weakens the structure of the nail. This coating is the result of the reaction between the iron and oxygen in the air (an oxidation reaction). If a 2.8 g nail (made of solid iron) is left outside, how many grams of iron (III) oxide (rust) will accumulate on the outside of the nail? 22. Magnesium hydroxide is a common ingredient in antacids.
