Answer:
1×
Explanation:
To solve this, you will need to do multiple steps.
Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.
Then, use the following formula to calculate the [OH-} concentration:
[OH-]= 
When converted to Scientific Notation<u>,</u> you get a resulting answer of
<u>1×</u><u>.</u>
<span>Answer:
CuX = Cu2+ + X2-
Ksp = [Cu2+] * [X2-]
for each mole of CuX that dissolves we get x mol of each of the anions and cations
Ksp = x^2 = 1.27 x 10 ^-36
x= 1.13 x 10 ^-18 moles of CuX per liter of pure water
if the solution has [Cu2+]= 0.27 M
Ksp becomes x ( x + 0.27)
as we can see above x is extremely small so can be ignored inside the brackets
0.27 x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.27 = 4.70 x 10 ^-36 moles per liter
In 0.19M X2- we have
Ksp = 0.19x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.19 = 6.68 x 10 ^-36 moles per liter</span>
Answer:
The answer to your question is:
Explanation:
Which formulas are incorrect:
NaO₂ Incorrect Na₂O correct
RbCl Correct
K₂S Correct
Al₂Cl₃ Incorrect AlCl₃ correct
MgP₂ Incorrect Mg₃P₂ correct
Salt
Explanation:
Of the listed substances, salts would have the highest melting point.
Salts are ionic compounds that are bounded by strong electrostatic forces.
In an ionic compound, metal and non-metal bond together through electrostatic attraction of their ions.
- Melting point is a property induced but intermolecular forces.
- It is known that salts have very strong intermolecular forces between them.
- They exhibit ionic crystal lattice forces.
- They are the strongest forces.
- They are strong electrostatic attraction between oppositely charged ions arranged into a crystal lattice of ionic compounds.
