WebIn a chemical reaction, the reactant that is consumed first and limits how much product can be formed is called the limiting reactant (or limiting reagent). In this video, we'll determine the limiting reactant for a given reaction and use this information to calculate the theoretical yield of product. Created by Sal Khan. WebOct 23, 2015 · Oxygen. Start by taking a look at the balanced chemical equation for this reaction color(red)(2)"H"_text(2(g]) + "O"_text(2(g]) -> 2"H"_2"O"_text((l]) Notice that you have a color(red)(2):1 mole ratio between hydrogen gas and oxygen gas. This means that, regardless of how many moles of oxygen gas you have, the reaction needs twice as many …
