1) mol fraction of gas X= 2/(6+2)=2/8=1/4
2) mol fraction of gas Y= 6/(6+2)=6/8=3/4
3) Partial pressure of X = 1/4*2.1 atm=0.53 atm
4) Partial pressure of Y = 3/4*2.1=1.6 atm
Answer:
The answer is B i think, sorry if im wrong
Explanation:
To find the number of electrons in a neutral gold atom look at it's atomic number. The atomic number is the number of protons in the element. For an atom to be neutral it needs the same number of electrons as protons, therefore the positive and negative charges will be balanced out. Gold's atomic number is 79 therefore it has 79 electrons.
Answer:
Gas to liquid
Explanation:
As the atoms temperature decreases, the kinetic energy of the atom decreases. Besides if it is turning to solid the atoms will be fixed position,they wont pass each other. So it here is forming to become a liquid
