DEFINE WORK |
THE RESULT OF ANY CHANGE IN ENERGY CAN BE MEASURED QUANTITATIVELY THROUGH JOULES OR CALORIES |
|
|
DEFINE KINETIC ENERGY |
THE AMOUNT OF ENERGY ASSOCIATED WITH AN OBJECTS MOTION AKA ENERGY OF MOTION DOUBLING VELOCITY QUADRUPLES KINETIC ENERGY |
|
|
WHAT IS THE FORMULA FOR CALCULATING KINETIC ENERGY |
KE= 1/2MV SQUARED |
|
|
DEFINE POTENTIAL ENERGY
|
AKA STORED ENERGY AMOUNT OF ENERGY STORED IN AN OBJECT |
|
|
WHAT IS THE FORMULA FOR CALCULATING STORED ENERGY |
PE= mgh m= mass of object g= gravity constant or 9.8 meters per second squared h= height at which object is located |
|
|
DEFINE MATTER |
MATTER IS ANYTHING THAT TAKES UP SPACE AND HAS MASS |
|
|
DEFINE MASS
|
THE QUANTITY OF MATTER THAT AN OBJECT HAS |
|
|
DEFINE AN ELEMENT |
OVER 100 SUBSTANCES THAT CANNOT BE BROKEN DOWN INTO SIMPLER SUBSTANCES |
|
|
HOW DO YOU FIND THE ATOMIC NUMBER OF AN ELEMENT |
IT IS THE SAME AS THE NUMBER OF PROTONS IN THAT ELEMENT |
|
|
DEFINE AN ION |
AN UNBALANCED ATOM THAT IS EITHER POSITIVELY OR NEGATIVELY CHARGED |
|
|
HOW DO YOU CALCULATE THE ATOMIC MASS OF AN ATOM |
BY ADDING THE NUMBER OF PROTONS AND NEUTRONS TOGETHER ELECTRONS HAVE ALMOST 0 MASS |
|
|
DEFINE A CATALYST |
CONTROLS THE RATE OF A CHEMICAL REACTION |
|
|
DEFINE SUBSTRATE |
MOLECULAR SURFACE ACTED UPON BY AN ENZYME SURFACE AREA |
|
|
DEFINE ACTIVATION ENERGY |
ENERGY NECESSARY FOR A CHEMICAL REACTION TO TAKE PLACE |
|
|
THE PERIODIC TABLE IS ORGANIZED IN TO WHAT |
INTO ROWS AND COLUMNS |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED |
FROM LEFT TO RIGHT ACROSS A ROW THE NUMBER OR PROTONS AND ELECTRONS INCREASE WHICH ALSO INCREASES THE NUCLEAR CHARGE AND ATOMIC RADII |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED |
AS YOU MOVE DOWN A COLUMN THE # OF ELECTRONS AND ELECTRON FILLED SHELLS INCREASES ALSO INCREASING THE ATOMIC RADII AND NUCLEAR CHARGE |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED
|
IONIZATION ENERGY OR IONIZATION POTENTIAL INCREASES FROM LEFT TO RIGHT |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED
|
WITHIN A GROUP ELECTRONEGATIVITY (WHICH GOES HAND IN HAND WITH IONIZATION) DECREASES AS ATOMIC NUMBER INCREASES |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED
|
EACH COLUMN IS A FAMILY WITH SIMILAIR PROPERTIES |
|
|
EXPLAIN A WAY THE PERIODIC TABLE IS ORGANIZED
|
TO THE LEFT OF THE STAIRCASE ARE METALS AND TO THE RIGHT ARE NON METALS TOUCHING THE STAIRCASE ARE METALLOIDS |
|
|
DEFINE AN ENZYME |
A NATURAL/BILOGICAL CATALYST ACTING TO BREAK DOWN PROTEINS CARBOHYDRATES FATS AND OTHER NUTRIENTS ARE RESPONSIBLE FOR THOUSANDS OF CHEMICAL REACTIONS WITHIN THE HUMAN BODY |
|
|
DEFINE A pH VALUE |
MEASURE OF HYDROGEN ION CONCENTRATION IN A SOLUTION MEASURE OF HOW ACIDIC OR BASIC A SOLUTION IS |
|
|
DEFINE WHEN A SOLUTION IS CONSIDERED BASIC , ACIDIC AND WHAT THE NEUTRALITY STANDARD IS |
BASIC IS A pH VALUE ABOVE 7 ACIDIC IS A pH VALUE BELOW 7 PURE WATER IS THE STANDARD OF NEUTRALITY |
|
|
A DIFFERENCE OF ONE UNIT ON THE pH SCALE REPRESENTS WHAT? |
A DIFFERENCE OF 10 |
|
|
WATER IS WHAT KIND OF MOLECULE |
A POLAR MOLECULE |
