| THE TOTAL NUMBER OF PROTONS AND NEUTRONS IN AN ATOM |
|
|
Term
|

| ARE IONS,MOLECULES OR ATOMS WITH UNPAIRED ELECTRONS WITH AN OPEN SHELL. *THESE ARE KNOWN TO CAUSE DEGENERTIVE DESEASES AS WELL AS AGING |

| LAW OF CONSERVATION OF ENERGY |
|
Definition
| THIS LAW STATES THAT NO ENERGY IS LOST OR USED UP ONLY THAT IT IS CHANGED FROM ONE FORM TO ANOTHER-SUCH AS WHEN YOU SHIVER YOUR MUSCLE CREATE HEAT TO MAKE YOUR WARM BY USING UP ATP |

Term
| 4 TYPES OF CHEMICAL REACTIONS |
|
Definition
1:SYNTHESIS-REACTANTS A AND B COMBINE TO FORM THE MOLECULE AB WHICH HOLDS ENERGY IN ITS BONDS
2:DECOMPOSITION REACTIONS:BREAK DOWN OF MOLECULES TO A SIMPLER FORM SUCH AS MOLECULE AB DOWN TO ATOM A AND ATOM B
3:EXCHANGE REACTIONS-THESE REACTIONS INVOLVE BOTH SYNTHESYS AND DECOMPOSITION REACTIONS TO FORM NEW MOLECULES SUCH AS AB+CD=AD+BC\
4:REVERSIBLE REACTIONS-REACTIONS THAT CAN BE USED TO STORE ENERGY AND THEN BE BROKEN DOWN AGAIN WHEN THAT ENERGY IS NEEDED

WATER AS A SOLVENT
WHY IS IT SUCH A GOOD SOLVENT? |
|
Definition
| WATER MOLECULES HAVE TWO POLAR SIDES A POSITIVE AND A NEGATIVE. THERE ARE ALSO A LOT OF MOLECULES OF WATER WHICH ALLOW IT TO SORROUND OTHER COMPOUNDS AND MOLECULES AND THEN BREAK APART OTHER WEAKER BONDS SUCH AS WHEN SODIUM CHLORIDE IS ADDED TO WATER. |
