Law of Conservation of Mass Example

The video introduces the concept that the mass of reactants before a chemical reaction is equal to the mass of the products after the reaction. It states that mass is neither created nor destroyed in chemical reactions, a principle established by a French chemist in 1789.

Using baking soda and vinegar, the video illustrates the law. Initially, the reactants have a combined mass of 113 grams. After the reaction, which produces gas, the total mass of the products remains 113 grams, confirming that mass is conserved and merely rearranged.

The balanced chemical equation for the reaction is presented, showing how the elements are balanced and rearranged on both sides. The video concludes by highlighting that this everyday example of baking soda and vinegar clearly demonstrates the Law of Conservation of Mass in action.
