When iron (Fe) reacts with molecular oxygen (O2), a new compound is formed. This compound is the Fe2O3 found in rust. 4 Fe +3 02 - 2 Fe2O3
If 112 g of Fe combines with 48 g of Oz, how much Fe2O3 is formed?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
