This uses something called the combined gas law. The combined gas law is as follows: (P1*V1/T1) = (P2*V2/T2)
According to question 2, you are given the following values initially:
P1 = 680 mm Hg * (1 atm/760 mm Hg) = 0.895 atm
V1 = 20.0 L
T1 = 293 K
STP or standard temperature and pressure implies that the other values we know are:
P2 = 1 atm
T2 = 273 K
Our unknown is V2
If we plug in our known values into the combined gas law:
(P1*V1/T1) = (P2*V2/T2)
(0.895 atm * 20.0 L)/293K = (1 atm * X liters)/273 K
0.0611 L*atm/K = (1 atm * X liters)/273 K
16.7 L = X liters
Therefore, the volume occupied at STP is 16.7 liters
This makes sense because the gas would occupy a smaller volume at a lower temperature, since the gas would have a lower average kinetic energy.
It's must have a slot for an electron to attach itself to the iodine atom
Answer:
heyy sure just use the unitary method to get the answer
photosynthesis: the process when plants make their own food using sunlight
When volume and pressures are given, it means we need to use Boyles' law formula--> P1V1 = P2V2
P1= 100 kPa
V1= 5.0 L
P2= 50 kPa
V2= ???
let's plug in the values.
(100 x 5.0) = (50 x V2)
V2= 10 L
