Answer:
6
Explanation:
Normally, oxygen has 8 electrons and 8 protons. If the charge is 2-, then that means there are two more protons than electrons. There would be 6 electrons.
Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
I think it takes about 2 weeks to go from H to B on the diagram since H is the new moon and B is the full moon so going from H to B represents half of the lunar cycle and one lunar cycle takes about 28 days (which is about 4 weeks).

Answer:
There is empty space between electrons and protons
Explanation:
The atom is composed of a nucleus and electrons that move round the shells in orbits. The electrons are negatively charged while the protons are positively charged.
In between the nucleus where protons are found and the electrons in orbits is largely empty space, hence the answer above.
