stoich exam Flashcards
gasses have the volume of what
their container
do gasses lose energy when colliding with walls or eachother
no
if a particle is not moving, what does this mean
it is at the absolute zero temperature where the kinetic energy of a particle is 0
what is the absolute zero
0k or -273 degrees
if you had a gas in a container and you were given the task to measure its volume, what would you do
measure the volume of the container
how is absolute zero found
by graphing the relationshipo between pressure and temp, the absolute zero can be extrapolated where there is 0 pressure and therefore no movement
what are the conditions for the ideal gas
1) the gas particles must have no volume ex) H2 O2 F2 and Co2 (smaller atoms)
Although real gasses all have a little volume
2) there must be no attraction between gas molecules.
Gasses closest to ideal (H2 He O2 F and Co2)
gases like H20 or molecules that have H bonds are NOT ideal due to strong forces
Although real gasses all have weak forces between molecules
why is the ideal gas law important
it relates pressure volume moles and temp all together
STP CONDITIONS
101.3 kpa
273K
state what boyles charles and gay lussacs laws are
charles law states that at a constant number of moles and pressure, temperature and volume are directly proportional
boyles law states that at a temperature and number of moles, pressure and volume are directly related to eachother
gay lusscas law states that as you keep volume constant and number of moles, pressure and temperature are directly proportional
whta is NOT soluble vs what is
group one metal, nittrates, acetete (CH3COO) is soluble
Pb Ag Co3 OH Sulfur is insoluble
describe precipitation
it is when 2 ionic compounds or salts come together to form a insoluble salt
