Answer:
solubility of X in water at 17.0 
is 0.11 g/mL.
Explanation:
Yes, the solubility of X in water at 17.0 can be calculated using the information given.
Let's assume solubility of X in water at 17.0 is y g/mL
The geochemist ultimately got 3.96 g of crystals of X after evaporating the diluted solution made by diluting the 36.0 mL of stock solution.
So, solubility of X in 1 mL of water = y g
Hence, solubility of X in 36.0 mL of water = 36y g
So, 36y = 3.96
or, y = 
= 0.11
Hence solubility of X in water at 17.0 is 0.11 g/mL.
Answer : The correct option is, (a) 345 K
Explanation :
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree Celsius is, 72
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in Kelvin is, 345 K
Atoms combine as the electrons from each atom are attracted to the nuclei of the atoms. The results in bonds ranging from 100%covalent to bonds with higher character. The combination of atoms to form compounds occurs when the compounds being formed are at lower energy than the original atoms. In chemical change, the molecules in the reactants interact to form new substances.
Answer:
m-CPBA followed by base catalysed hydrolysis
Explanation:
The scheme of this reaction is shown in the image attached.
We can see here that the acetophenone reacts with metachloroperoxybenzoic acid (m-CPBA) as shown in the image to yield phenyl acetate.
Phenyl acetate is now hydrolysed by a base as shown to yield the acetate ion and phenol.
