The document discusses the law of conservation of matter, which states that the total mass of a chemical reaction remains the same even as the substances change form. It provides examples like rust forming or cooking eggs, where the total mass before and after the reaction is equal. The document also shows a chemical equation of methane and oxygen reacting to form carbon dioxide and water, with the total mass on both sides of the equation being equal.

4. Another example would be when you cook something like eggs or you bake bread it will still weigh the same when it's done.

6. Even though the chemicals have reacted and changed into something completely different there is still the same amount of mass.
