Neutrons are found in the nucleus and separate the other particles so that the strong force can hold the nucleus together. Which
particles are positively charged and need to be separated so that they don't repel?
A) electrons
B) neutrons
C) protons
D) quarks
A) electrons
B) neutrons
C) protons
D) quarks
2 answers:
Answer:
C) protons
Explanation:
The atom of most elements have proton and neutron located in the nucleus while the electron resides in the outer part of an atom.
The proton are usually positively charge and tends to repel one another in the nucleus of an atom. The reason for the repel of the proton is the positively charged nature. The neutron has no charge because they are neutral. The neutron are usually heavier than the proton . The sum of the proton and neutron contributes mostly to the mass of an atom. The electron that revolves and reside at the outer part of an atom is negatively charge.
The picture above is a representation of how the proton, electron and neutron is located in an atom.

Answer : The mole fraction and partial pressure of and
gases are, 0.267, 0.179, 0.554 and 1.54, 1.03 and 3.20 atm respectively.
Explanation : Given,
Moles of = 1.79 mole
Moles of = 1.20 mole
Moles of = 3.71 mole
Now we have to calculate the mole fraction of and
gases.
and,
and,
Thus, the mole fraction of and
gases are, 0.267, 0.179 and 0.554 respectively.
Now we have to calculate the partial pressure of and
gases.
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas = 5.78 atm
= mole fraction of gas
and,
and,
Thus, the partial pressure of and
gases are, 1.54, 1.03 and 3.20 atm respectively.
