Answer:
is the solubility of 
in 0.10 M 
.
Explanation:
Concentration of calcium nitrate = ![[Ca(NO_3)_2]=0.10 M](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M)
![[Ca(NO_3)_2]=0.10 M=[Ca^{2+}]](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M%3D%5BCa%5E%7B2%2B%7D%5D)
Solubility product of the calcium fluoride = 
Solubility of calcium fluoride in calcium nitrate solution :
(0.10+S) (2S)
The expression of solubility is given by :
![K_{sp}=[Ca^{2+}][F^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2)
Solving for S:
is the solubility of in 0.10 M .
Answer:
207g
Explanation:
Given compound:
Ca(ClO₃)₂
Equivalent mass is the
The equivalent mass can be derived by summing the molar masses of each atom
Molar mass of Ca = 40
Cl = 35.5
O = 16
Now solve;
Molar mass = 40 + 2(35.5 + 3(16)) = 207g
The Cambrian period I think
Answer:
1, 2 & 3
Explanation:
. A chemist investigates the boiling point, melting point, and flammability
of a compound called acetone, a component of nail polish remover.
Which of these properties are physical properties and which are
chemical properties?
Physical ( boiling point and melting point ).
Chemical ( flammability )
It would have THREE rings/energy levels. This is because of the amount of electrons each orbital can hold.
