2.8g of iron (¡¡) reacted with 100ml of 2M sulfuric acid. Which reactant is in excess? And what volume of hydrogen gas is produced at RTP?
Limiting reagent problems are handled almost the same as regular stoichiometry problems.
Use one reagent and calculate the mols of one of the products.
Use the other reagent and calculate the mols of the same product.
The SMALLER value of the mols of product will be the correct one.
Continue with the problem from there.
Post your work if you get stuck.
