Overview: |
In this lesson, students will analyze the chemical equation for the reaction between vinegar (acetic acid solution) and baking soda (sodium bicarbonate). They will make the connection between the written chemical equation, the molecular model, and the real substances in the reaction. Students will see that the gas produced in the actual reaction is also written in the products of the equation. Students will also change the amount of one or more reactants and see how the change affects the amount of products.
Students will be able to explain that for a chemical reaction to take place, the bonds between atoms in the reactants are broken, the atoms rearrange, and new bonds between the atoms are formed to make the products. Students will be able to count the number of atoms on the reactant side and on the product side of a chemical equation. They will also be able to explain that the equal number of atoms on each side of the equation shows that mass is conserved during a chemical reaction. Students will also be able to explain, on the molecular level, why changing the amount of one or more reactants changes the amount of products. They will also be able to explain why simply adding more and more of one reactant will eventually not produce additional products. |
Content Standard(s): |
Science SC2015 (2015) Grade: 8 Physical Science | 6 ) Create a model, diagram, or digital simulation to describe conservation of mass in a chemical reaction and explain the resulting differences between products and reactants.
