Data:
C1 (initial concentration) = 7.5 g/L
P1 (initial pressure) = 404 kPa
C2 (final concentration) = ? (g/L)
P2 (final pressure) = 202 kPa
We apply the data to the formula of the solubility of gases in a liquid (Henry's Law), let us see:
Solving:
I hope this helps. =)
F=Gm1m2/D*2
or,2.0×10^-7 = (6.67×10^-11 ×75×90)/D^2
or,2.0×10^-7 = (45022.5×10^-11)/D^2
or,D^2=22511.25×10^-4
D=1.5003m
Answer:
Explanation:
Hello!
In this case, according to the gas laws, we would be able to assume HCl can be modeled as an ideal gas for this calculation purpose; in such a way, we use the following equation to compute the temperature:
In such a way, we plug in moles, volume and pressure to obtain:
Best regards!
I believe the correct answer from the choices listed above is the third option. The kinetic theory explains that heat is due to the motion of molecules. Temperature is the measurement used to measure heat and is directly proportional to the average kinetic energy of the molecules.
Answer:
Explanation:
When heat is supplied to a substance, the temperature of the substance increases according to:
where
Q is the amount of heat supplied
m is the mass of the substance
C is the specific heat capacity of the substance
is the initial temperature
is the final temperature
For the sample of magnesium in this problem, we have:
m = 63 g is the mass
Q = 6689 J is the hear supplied
C = 1.023 J/gC is the specific heat capacity
is the final temperature
Solving the formula for , we find the final temperature:
