Conservation of Mass in Chemical Reactions

Conservation of Mass in Chemical Reactions

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of reactants must always equal the total mass of products. Atoms are rearranged to form new substances, but their total quantity remains unchang...

In the 1700s, French scientist Antoine Lavoisier asked interesting questions, like: Does matter disappear during a chemical reaction?

To find this out, he conducted experiments by sealing substances in glass jars to ensure nothing—not even gases could escape. By measuring the mass before and after the reactions, he found that the total mas...
