Student Exploration: Limiting Reactants Keyaira Beck Vocabulary: chemical equation, chemical formula, chemical reaction, coefficient, limiting reactant, molecule, product, reactant, subscript Prio ... r Knowledge Questions (Answer these questions BEFORE using the Gizmo.) Imagine you and your friends are making hot dogs. A complete hot dog consists of a frankfurter and a bun. At the store, you buy four packages of eight frankfurters and three bags of 10 buns. 1. How many hot dogs can you make? I can make 30 hotdogs. 2. Which ingredient limited the number of hot dogs you could make? Buns limited the number of hot dogs I can make. 3. Which ingredient will you have leftovers of? I will have 2 leftover hotdogs. Gizmo Warm-up Just as ingredients can be put together to make new food items, 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. To begin, make sure H2 + O2 becomes H2O is selected. The small “2” in H2, O2, and H2O is a subscript. Subscripts represent the number of atoms in a molecule. 1. Use the sliders to set the number of O2 molecules and H2 molecules to 2. A. A. How many hydrogen molecules (H2) are there? 1 Hydrogen atoms? 2 A. B. How many oxygen molecules (O2) are there? 1 Oxygen atoms? 2 2. How many H2O molecules do you think will form when these 4 molecules react? 2 3. Click Play (). How many H2O molecules actually formed? 2 This study source was downloaded by 100000819946675 from CourseHero.com on 03-25-2021 13:13:15 GMT -05:00 https://www.coursehero.com/file/42620388/student-exploration-limiting-reactions-Keyaira-Beckdocx/ This study resource was shared vi [Show More]
