Vocabulary: chemical equation, ch... emical formula, chemical reaction, coefficient, limiting reactant, molecule, product, reactant, subscript Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Imagine you and your friends are making hot dogs. A complete hot dog consists of a wiener and a bun. At the store, you buy four packages of eight wieners and three bags of 10 buns. 1. How many total hot dogs can you make? 30 hotdogs 2. Which ingredient limited the number of hot dogs you could make? the buns 3. Which ingredient will you have leftovers of? hotdogs Gizmo Warm-up Just as ingredients can be put together to make a new food, substances can combine during a chemical reaction to produce new substances. The substances that undergo change are called reactants. The new substances are products. Sometimes during a chemical reaction, one type of reactant will be used up before the other reactants. This reactant is the limiting reactant. Using the Limiting Reactants Gizmo, you can determine which reactant is limiting in various scenarios. [Show More]
