Answer: 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the 
is given as:
When the solubility of is S moles/liter, then the solubility of 
will be S moles/liter and solubility of 
will be 2S moles/liter.
By stoichiometry of the reaction:
1 mole of gives 1 mole of 
and 2 moles of
![K_{sp}=[Ba^{2+}][F^{-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BBa%5E%7B2%2B%7D%5D%5BF%5E%7B-%7D%5D%5E2)
Thus 
for is
Either NaI or INa are acceptable formulae for sodium iodide, which is indeed a binary ionic compound. So, the correct answer would be B.
Hey there!:
Given [ OH⁻ ] = 9.00 x 10⁻⁴
We know that : [H⁺ ] [OH⁻ ] = 1 x 10⁻¹⁴
Thus [H⁺ ] = ( 1 x 10⁻¹⁴ ) / ( 9.00 x 10⁻⁴ )
[ H⁺ ] = 1 x 10⁻¹¹ M
therefore:
pH = - log [ H⁺ ]
pH = - log [ 1 x 10⁻¹¹ ]
pH = 10.95
Therfore pH = 10.95
I hope this will help !
Answer:
All molecules of a compound have the same properties. The chemical properties of any individual compound would not change. The molecule is one of the smallest particles in any element that has the chemical properties of that element. Molecules are made of atoms.
I think the correct answer from the choices listed above is option A. It is the salt bridge that balances charges that may build up as reduction and oxidation occur in a voltaic cell. The salt bridge is to <span>maintain charge balance because the electrons are moving from one half cell to the other.</span>
