The major difference is A, because astrology is a pseudoscience, and that sets it apart from astronomy more than D.
Oxygen has the atomic number 8, which eliminates options B and D right away. Any neutral atom, including the oxygen atom, has the same number of protons and electrons, meaning the number of electrons is also 8. If you're still not sold, the oxygen atom has a mass number of 16, which is the sum of the protons and neutrons in the atom, meaning there have to be 8 neutrons as well. The answer is option A.
As the given equation is
AgNO3 = Ag+ + NO3-
split it then derive the
the Ksp expression.
Ksp = [Ag+] [NO3-]
Since there is 1:1 molar ratio,so by applying values
<span>1.8E^-10 = (s)(s)
</span><span>1.8E^-10 = s^2
</span><span>s=1.34 x 10^-5 M
this is the solubility of silver chloride
hope it helps</span>
Density = mass/volume = 316/22.5 = 14.045g/mL.
