AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
Ksp=[A²⁺][B⁻]²
a=1.10 g/L
M=169 g/mol
c=a/M
[A²⁺]=c=a/M
[B⁻]=2c=2a/M
Ksp=(a/M)(2a/M)²=4(a/M)³
Ksp=4*(1.10/169)³=1.103×10⁻⁶
They are evnly mixed on the atmotic level but not bonded together.Another nae for a mixture is solution.
It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
Answer:
kilogram
Explanation:
because kilogram is equal to thousand grams
In the Lewis symbol for a fluorine atom, there are <u>4</u> paired and <u>1</u> unpaired electrons.
However, paired electrons simply means are 2 electrons occupying the same orbital in an atom or molecule of a substance
On the other end, unpaired electron is a single electron that occupies an orbital of an atom.
<h3>What is an atom?</h3>
An atom is the smallest part of an element which can take part in a chemical reaction.
Some atoms of elements are:
- Monoatomic
- Diatomic
- Triatomic
- Polyatomic
In conclusion, in the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.
