C. Protons
Protons are subatomic particles found in the nucleus and carry positive electrical charge.
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:
The system is a portion of the universe that you separate to study it. It doesn't have to be a physical separation, you determine the boundaries of the system or a given problem has them determined. A machine, a rock, a room or a person can be defined as a system.
The surrounding is the rest of the universe that is not part of the system. So system + surrounding = universe.
Any products of the system are ouputs, these leave the system and are no longer part of it, therefore they are part of the surrounding.
