Answer: The mole fraction of neon in the final mixture is 0.6
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 5.0 atm
= partial pressure of argon = 2.0 atm
= partial pressure of Neon = ? atm
According to Raoults law, the partial pressure of a gas is equal to its mole fraction mulitiplied by the total pressure.
= mole fraction of Neon
Thus mole fraction of neon in the final mixture is 0.6
Answer: Option (D) is the correct answer.
Explanation:
An electric circuit works well when all the connections are complete but if any of the connections in the circuit is loose or disconnected then it is possible that current will not flow from the circuit.
Therefore, when Jenna removed one of the clips on the battery then circuit becomes incomplete and as a result there will no flow of current.
Thus, we can conclude that the electrical energy would stop because the circuit is incomplete.
Answer:
Number of atoms =1.806×10²⁴
Explanation:
You have the number of moles of Carbon tetrachloride which is n=3
And you are looking for number of atoms that are in the sample, which are represented by the letter "N"
The formula that has both number of moles(n) and number of atoms(N) is written as n=N/Na
Na is called the Avogadros number and it is equal to 6.08×10²³, it never changes(it is a constant)
So you will substitute the number of moles and the avogadros number to you formula, and the only unknown will be the number of atoms which you are looking for
- n=N/Na
- 3=N(6.02×10²³)
- N=1.806×10²⁴ atoms of CCl
NB: N does not represent the number of atoms only. It may also represent the number of particles or molecules...
