Answer:
I would expect to extract the acetic acid.
Explanation:
In the first step, since we are adding a concentrated acid,<u> it will react with the bases present in the mixture (diethylamine and ammonia) </u><u>forming salts</u><u>, </u><u>which are soluble in water</u>. Therefore, after draining the aqueous layer, we will have phenol and acetic acid left in the organic layer.
In the second step, we are adding a diluted base, so it will react with a strong acid. This compound is acetic acid, and its salt will be present in the aqueous layer. Phenol will be left on the organic layer.
Answer:
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
A mixture is easily separated like a salad where you can pick things out and a compound you are usually unable to undo.
Answer: The value of equilibrium constant for the given reaction is,
Explanation:
The given chemical equation is:
;
We need to calculate the equilibrium constant for the chemical equation, which is:
;
If the equation is revered then the equilibrium constant will be the reciprocal of the reaction.
If the equation is half then the equilibrium constant will be square-root of the reaction.
The value of equilibrium constant for the given reaction is:
Hence, the value of equilibrium constant for the given reaction is,
Answer:
Since the melting point of iron (1538 C) is higher than the Curie point (770 C), the recast iron will lose its original magnetism. After the iron has cooled below the Curie point, it can be re-magnetized.
