As you know ethanol is a an alcohol and alcohol is a hydrocarbon. Alcohol is made up of a carbon chain which Is always non polar and a OH group which is polar. According to the solubility rule like substances dissolves like substance. Using ethanol chemical formula. Ethanol has a 2 carbon chain and a OH group. water is polar so it will be attracted to the OH group. Carbon chain on the other hand is nonpolar so it will be repelled from the water.
Therefore the Solubility of alcohols is determined by the stronger of the two forces. The strength of the attraction of the OH group, and the amount of water they dissolve in.
A.
The first energy level has 2 electrons, the second has 8, and the third has 4
Answer:
gypsum
Explanation:
gypsum is used to make plaster of Paris
The solubility of the compound is obtained as 9.5 * 10^-14 M.
<h3>What is the solubility product?</h3>
The solubility product refers to the equilibrium constant that shows the extent to which a thing is soluble in water, Now we can write the solubility product as;
Ksp = [Hg^2+] [2OH^-]^2
Let [Hg^2+] = [OH^-] = x
Then I can write;
Ksp = x * (2x)^2
Ksp = 4x^3
When x = solubility
x = ∛Ksp/4
Ksp = 3.60×10^−26
x = ∛ 3.60×10^−26/4
x = 9.5 * 10^-14 M
