chemical reaction notes
A chemical reaction occurs when atoms separate, come together, or rearrange to form new substances with new properties.
Solid is called a precipitate.
A chemical reaction can be seen in rust, tarnishing, and carbonated drinks.
Molecule:
-atoms that combine with other atoms to form larger units
Compound:
-two elements chemically combine to form an new substance totally different from the elements that make up the compound
-example: Salt= Na + C1 --> NaC1
all compounds are molecules but not all molecules are compounds
SUGAR: C6H12O6 MEMORIZE
