<u>Answer:</u>
<u>For Part A:</u> The partial pressure of Helium is 218 mmHg.
<u>For Part B:</u> The mass of helium gas is 0.504 g.
<u>Explanation:</u>
We are given:
To calculate the partial pressure of helium, we use the formula:
Putting values in above equation, we get:
Hence, the partial pressure of Helium is 218 mmHg.
To calculate the mass of helium gas, we use the equation given by ideal gas:
PV = nRT
or,
where,
P = Pressure of helium gas = 218 mmHg
V = Volume of the helium gas = 10.2 L
m = Mass of helium gas = ? g
M = Molar mass of helium gas = 4 g/mol
R = Gas constant = 
T = Temperature of helium gas = 283 K
Putting values in above equation, we get:
Hence, the mass of helium gas is 0.504 g.
Answer:
xy (-b+c+q) is the answer to this
There are a lot of separation processes. To name a few, these can be distillation, centrifugation, extraction, membrane or sorption process and many other. To know which is the best technique, you should know the property between two substances that have a stark difference. In this case, it is the polarity. Ethyl alcohol is more polar than ethyl ester and less dense. Thus, these two won't mix. So, take advantage of their density difference by decantation or centrifugation.
Answer:
True
Explanation:
The more of each substanse that you add to the bag will cause it to produce faster and more gas.
Answer:
a) A microstate is a snapshot of positions and speeds at a particular instant.
b) A thermodynamic state is a single possible arrangement of the positions and kinetic energies of the molecules.
c) A thermodynamic state is a set of conditions, usually temperature and pressure, that defines the properties of a bulk material.
d) A microstate is a single possibility for all the positions and kinetic energies of all the molecules in a sample.
e) A thermodynamic state is a set of conditions, usually temperature, volume and number of moles, that defines the properties of a bulk material.
Explanation:
A state of a system in thermodynamics give the properties that a material is been made up, these properties could be pressure, temperature, volumes and others , they are been called thermodynamic property
Microstates helps us to know how molecules is been arranged in single instant. Kinetics energy as well as position of molecules in a particular substance can be known in single instant.
