Note: If any of the liquid splashes out during heating, stop and discard the contents of that test tube. We had just finished our reactions unit, so they were all familiar with the generalized pattern that a decomposition reaction follows. Asking questions and defining problems in grades 9–12 builds from grades K–8 experiences and progresses to formulating, refining, and evaluating empirically testable questions and design problems using models and simulations. Continue to project the chemical equation as you and students count the number of atoms on both the reactant side and product side of the equation. What is the gas produced in the chemical reaction between vinegar and baking soda?
Baking Soda Stoichiometry Lab Answer Key Quizlet
You can use three options; typing, drawing, or capturing one. Modeling in 9–12 builds on K–8 and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed worlds.
