Because substances are made up of different atoms and molecules, they react in characteristic ways. Production of a gas, color changes, a change in temperature, and the formation of a precipitate are ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...
