Take note 📝 (LAW OF CONSERVATION OF MASS)

He found that no matter what reaction he looked at, the mass of the starting materials was always equal to the mass of the ending materials. This is now called the law of conservation of mass.

The work of several scientists and their experimental data gave evidence for what is now called the atomic theory. In the late 1700’s, Antoine Lavoisier, a French scientist, experimented with the reactions of many metals. He carefully measured the mass of a substance before reacting and again measured the mass after a reaction had occurred in a closed system (meaning that nothing could enter or leave the container).

Dalton's Atomic Theory Although the concept of atoms is now widely accepted, this wasn’t always the case. Scientists didn’t always believe that everything was composed of small particles called atoms.

Introduction You learned earlier how all matter in the universe is made out of tiny building blocks called atoms. All modern scientists accept the concept of the atom, but when the concept of the atom was first proposed about 2,500 years ago, ancient philosophers laughed at the idea. It has always been difficult to convince people of the existence of things that are too small to see. We will spend some time considering the evidence (observations) that convince
