1. Compound - Correct Answer: a substance formed when two or more
elements are chemically bonded together
2. Organic compounds - Correct Answer: compounds that contain the
element carbon.
3. inorganic compound - Correct Answer: compounds that do not contain
the element carbon
4. Macromolecules - Correct Answer: carbohydrates, lipids, proteins,
nucleic acids
are important because they are involved in all of the structures and
processes of cells and organisms.
5. 4 organic compounds - Correct Answer: CHON: carbon, hydrogen,
oxygen, and nitrogen which are all found in 96/ of all life on earth.
,6. valence number - Correct Answer: the number of electrons that an
atom gains or loses when combining with other atoms
7. Evidence of a chemical reaction - Correct Answer: a chemical reaction
has occurred if any of the following take place: unexpected temperature
change, unexpected color change, production of gas, change in odor, or
formation of a precipitate
8. Mixtures - Correct Answer: when different substances are combined but
do not react chemically.
can be separated in the following ways: hand separation, filtration, and
distillation
9. Distillation - Correct Answer: A process that separates the substances in
a solution based on their boiling points
10.Solutions - Correct Answer: made of a solvent and a solute
11.Solvent - Correct Answer: the liwquid into which something is dissolved
(i.e. water)
12.Solute - Correct Answer: a solid, gas, or liquid that is dissolved into the
solvent to make a solution.
,13.the pH scale - Correct Answer: scale with values from 0 to 14, used to
measure the concentration of H+ ions in a solution; a pH of 0 to 7 is acidic, a
pH of 7 is neutral, and a pH of 7 to 14 is basic
14.Acid - Correct Answer: a solution in which the number of hydronium ion
is greater than the number of hydroxide ions (OH-)
have a sour taste and corrosive.
15.Bases - Correct Answer: a solution that contains more hydroxide ions
(OH-) than hydronium ions (h3o+)
they have bitter taste and feel slippery.
16.buffer - Correct Answer: a chemical substance that neutralize small
amounts of either an acid or base.
17.Litmus paper - Correct Answer: an indicator paper that turns red in an
acid and blue in a base
18.Position - Correct Answer: where an object is located in space
19.Displacement - Correct Answer: difference between the initial and
straight from the beginning point to the end.
the position from start or the net change in position of an object in motion
20.Distance - Correct Answer: an objects total movement.
the total amount of ground covered byan object in motion
, 21.Speed - Correct Answer: the rate at which an object is able to move or
operate. It is the distance traveled per unit of time.
s=d/t
22.velocity - Correct Answer: the rate of speed in a certain directions; it
measures how fast an object gets somewhere. calculated by dividing
distance travelebed in meters or seconds.
v=d/t
23.acceleration - Correct Answer: when velocity of an object changes,, an
object which is slowing down is expereinces a negative acceleration or
deceleration.
acceleration (a)= v/t
24.First Law of Motion - Correct Answer: 1) an object moving will keep
moving
2) if an object is at rest, it will stay at rest unless acted on by an unbalanced
force.
25.Inertia - Correct Answer: the tendency of an object in motion to remain
in motion.
ex: Jenga
26.Newton's second law of motion - Correct Answer: the acceleration of an
object is in the same direction as the net force on the object and can be
calculated in a few ways.
