"In a chemical reaction, no matter is created or destroyed, but instead changes form."
Lavoisier's Conservation of Mass
Concept #1: Law of Conservation of Mass
According to Lavoisier, all reactants are completely converted into products.
Example #1: How many grams of water vapor will form if 25.0 grams of hydrogen gas mixes with 12.0 grams of oxygen gas?
Practice: Predict the amount of oxygen gas that will remain after the reaction of 112.6 grams of calcium with 24.0 grams of oxygen.
