Crystsals can precipitate out of solution when some of the solvent is evaporated. For example, if you have sodium chloride in solution and you evaporate out the water some sodium chloride crystals will form. I hope this helps. Let me know if anything is unclear.
The equation is:
x * 20 + 0.12 * 60 = 0.10 * 80
20 x + 7.2 = 8
20 x = 8 - 7.2
20 x = 0.8
x = 0.8 : 20 = 0.04 ( or 4% )
Answer: B ) 0.04
When the salt AgI dissolves in water it dissociates as follows;
AgI ---> Ag⁺ + I⁻
molar solubility is the number of moles that are dissolved in 1 L of solution.
If molar solubility of AgI is x, then molar solubility of Ag⁺ is x and I⁻ is x.
the formula for solubility product constant - ksp of AgI is given below
ksp = [Ag⁺][I⁻]
ksp = (x)(x)
ksp = 8.51 x 10⁻¹⁷
therefore,
x² = 8.51 x 10⁻¹⁷
x = 9.22 x 10⁻⁹
since molar solubility of AgI is x, then molar solubility of AgI is 9.22 x 10⁻⁹ M
Answer:
Fructose
Explanation:
A ketose is a monosaccharide containing one ketone group (RCOR) per molecule.
This means to identify a ketose, one has to look for the ketone group in the structural formuar of the compound.
Mannose - This is an aldose. It contains the aldehyde functional group.
Galactose - This is an aldose. It contains the aldehyde functional group.
Fructose - This is a keose. It contains the Ketone Functional group.
Glucose - This is an aldose. It contains the aldehyde functional group.
