New cards
A physical property
is a characteristic (or feature) that can be measured or observed without changing the chemical identity Of Substance
23
New cards
chemical property
is a characteristic (or A future) exhibited, property measured or observed when a chemical reaction of a substance occurs; the identity of the substance changes
24
New cards
A chemical process/chemical reaction
Causes breakage (cleavage or dissociation) of covalent Chemical bonds and formation of new chemical bonds to produce a new substance. In some chemical reactions, electrons are exchanged between 2 substance.
25
New cards
extensive property
depends on the amount of substance measured
26
New cards
e.g. mass, volume
27
New cards
intensive property
does not depends on the amount of substance measured
28
New cards
e.g. density, temperature
29
New cards
mass
the quantity of matter in an object
30
New cards
volume
The amount of space that a sample occupies
31
New cards
precision
agreement among repeated measurements
32
New cards
(reproducibility)
33
New cards
accuracy
how close a measurement is to the true value
