Conservation of Mass Lab
Chemical Reaction: A process that involves rearrangement of the molecular or ionic structure of a substance; a chemical reaction is a process that produces a new substance without changing the number of subatomic particles.
The indicators of a chemical change are change in color, change in odor, change in temperature, formation of precipitate, and gas bubbles.

Mass before: 182 g
Mass after: 182 g
Reactants: C2H4O2 + NaHCO3 =
Products: NaC2H3O2 + H2O + CO2
Mass can neither be created or destroyed.
1. The evidence was the cold temperatures, the fizzing, and the formation of gas bubbles.
2. The final mass was the exact same as the initial mass. The law of conservation was not violated, because the weight remained the same.
3. for the reactants, C2HAO2 is vinegar and a liquid. Also, NaHCO3 is Baking Soda and is a sold. For the products, NaC2H3O2 is a solid; H2O is water and a liquid, and CO2 is Carbon Dioxide and is a gas.
