Document Summary
Stoichiometry: the calculation of amounts and masses of reactants and products in chemical reactions. Mass of starting material decreases, mass of products increases. 5. 7 reactions limited by the amount of one reactant. The sparkler (a wire coated with magnesium) burns in air, consuming oxygen until all of the magnesium has reacted https://onedrive. live. com/edit. aspx/documents/chemistry?cid=4612573e81e7633b&id=documents&wd=target%28september. one%7cfa2c53b9-0d 1/6. Magnesium is called the limiting reagent: it limits the formation of mgo(s) produced because it runs out in the sparkler, although more o2 is available in the air. Use o2 mols and stoichiometric ratios to determine the amount of no formed. Use o2 mols and ratios to determine the mol (and then mass) of nh3 reacted. Then add up mass of o2 and mass of nh3 reacted. Then add up mass of no and mass of h2o. Theoretical yield: the initial mass of reactants and the stoichiometry indicate the max amount of products that can be obtained.
