When solving problems involving stoichiometric coefficients, the first step is to make sure you have a balanced chemical equation. Then, you determine the limiting reagent by using the coefficients from the balancedequation. You can keep track of the amounts of all reactant and products before and after a reaction using an ICF table (as shown in the Simulation) Completing the ICF table will also allow you to determine the limitingreagent, and the amount of product formed is based on assuming that the reaction runs to completion with 100% yield Parts A and explore these steps in more detail. Let us consider another reactionAmmonia and oxygen react to form nitrogen monoxide and water Construct your own balanced equation to determine the amount of NO and H 0 that would form when 3 20 mol NH, and 535 mol O, readExpress the amounts in moles to two decimal places separated by a comma.
