CHEMICAL REACTION
|
a reaction that involves chemical changes in matter in new substances.
|
|
|
SOLUBILITY
|
max amount of a solute that dissolves withouit being changed in a reaction
|
|
|
REACTANT
|
one of the chemicals that comes together to react with other chemicals.
|
|
|
PRODUCT
|
is one of the chemicals you end up with after a chemical reaction
|
|
|
law of conservation of mass
|
mass cannot be created or destroyed
|
|
|
synthesis reaction

COMBINE:
3H2 + N2 = 2NH3 |
|
|
double-replacement
|
both switch places

single compound switches places
|
|
|
decomposition
|
decomp.
|
|
|
DIFFERENTIATE:
acid and base. |
ACIDS: are compounds that ionize. Litmus paper shows that acid is present by turning red.
BASE: Litmus paper turns blue when exposed to a base. |
|
|
SEVEN DIATOMIC ELEMENTS?
|
HOFBRINCL
|
|
|
ITEMS THAT HAVE AN EFFECT ON CHEMICAL REACTION?
|
reactants --> products
temp: KE surface area: contact area stirring: exposure concentration: more concentrated, faster catalysts: substances that speed up reaction w/o being changed in a reaction |
|

|
DISPLACEMENT
|
distance and direction of an objects position from starting point to ending point
|
|
|
SPEED
(and diff. types) |
distance an object travels per unit of time.
constant: doensn't change. average: speed of motino when speed is changing. instantaneous: at any given time |
|
|
VELOCITY
|
speed and direction of an objects motion.
|
|
|
ACCELERATION
|
the rate at which velocity changes
|
|
|
ACCELERATION CHANGES WHEN...
|
object:
speeds up slows down changes direction |
