kitchen chemistry also. In some recipes‚ baking soda‚ NaHCO3‚ is used to cause a cake to “rise”. When a weak acid such as vinegar‚ or buttermilk‚ or lemon juice is added to the baking soda‚ bubbles of carbon dioxide are produced. For example HC2H3O2 + NaHCO3 → H2O + CO2 + NaC2H3O2 Vinegar sodium sodium Bicarbonate acetate This release of gas is what causes the cake to increase in size. However‚ because baking soda tastes bitter and acids taste sour‚ it is

keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister - Vinegar - Water - Phone (as timer) - 2 Alka-Seltzer tablets - Electronic scale Procedure: 1. Fill the graduated cylinder with 10ml of vinegar and put it in the clean film canister. 2. Break the Alka-Seltzer tablets to two

The Law of Conservation of Mass Goals: 1. To identify the parts of a chemical equation. Students need to identify subscripts‚ coefficients‚ reactants‚ products‚ chemical formulas‚ and chemical symbols 2. To appreciate that scientific discoveries are often the result of inquiry. 3. to distinguish between an element‚ a compound‚ and a mixture (and between heterogeneous and homogeneous mixtures) 4. To balance a chemical equation in order to prove that the Law of Conservation of Mass works quantitatively as well as conceptually
