<u>Answer:</u> The amount of heat absorbed by the solution is 2.795 kJ
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = [70 + 70] = 140 mL
Putting values in above equation, we get:
To calculate the heat absorbed, we use the equation:
where,
q = heat absorbed
m = mass of water = 140 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature =
Putting values in above equation, we get:
Hence, the amount of heat absorbed by the solution is 2.795 kJ
Answer:
The student did not lose any organic product in the aqueous layer
Explanation:
From the question;
After addition of hydrochloric acid, a student removes the lower aqueous layer and extracts the aqueous phase with diethyl ether (0.5 mL).
The only possible way the student could have lose the product was if there are some basic group e.g in the compound which have a tendency of forming
salt.
Also these compound could be regenerated from aqueous layer by neutralizing the aqueous layer with basic solution , for example; by using sodium hydroxide (NaOH) in which the extraction is then followed by the usage of Diethyl ether.
