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.
Answer:
0.29 molL-1 or 0.29 M
Explanation:
Now we have to use the formula
n=CV
Where
n= number of moles = 0.87 moles
C= concentration of the solution (the unknown)
V= volume of the solution = 3.00L
Now having specified all parameters except the unknown (molarity if the sodium chloride solution) we can now proceed to find it.
C= n/V
C= 0.87mol/3.00L
C= 0.29 molL-1
Answer: The starting pressure of is 1.39 atm.
Explanation:
Initial p 0 0
eq'm p-x 0 2x
Total pressure at equilibrium = p - x + 2x = p + x = 1.9...(1)
...(2)
Solving equation (1) and (2). we get x = 0.51
p + x = 1.9
p= 1.9 - 0.51 = 1.39 atm
The starting pressure of is 1.39 atm.
The effect of temperature change on behaviour of gases varies directly, so the more temperature, the more movement of the molecules of the gas. I hope that answers your question!
