The reaction described above is the formation of an acetal. The initial starting material has a central carbonyl and two terminal alcohol functional groups. In the presence of acid, the carbonyl will become protonated, making the carbon of the carbonyl susceptible to nucleophilic attack from one of the alcohols. The alcohol substitutes onto the carbon of the carbonyl to provide us with the intermediate shown.
The intermediate will continue to react in the presence of acid and the -OH that was once the carbonyl will become protonated, turning it into a good leaving group. The protonated alcohol leaves and is substituted by the other terminal alcohol to give the final acetal product. The end result of the overall reaction is the loss of water from the original molecule to give the spiroacetal shown in the image provided.

Answer:
This compound is Ammonium Sulphide and has molar mass 68 g/mol.
Explanation:
- Molar Mass : It is the mass of 1 mole of the substance and in grams.Its units are gram/mole.
- It is numerically equal to mass of the substance in atomic mass units
How to calculate Molar mass :
grams/mole
Molar mass of Ammonium sulphide is 68 g/mol
Answer:
The body temperature would rise by 47.85 °C
The amount of water the body evaporates is 4.15 kg.
This makes sense because firstly the value obtained is positive then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature
Explanation:
Considering the relationship (between the heat released and the mass of the object) as shown below
q = msΔT
where q is the heat released per day =
m is the mass of the body = 50 kg
ΔT is the temperature rise = ?
s is the specific heat of water =
substituting values we have
=
ΔT
ΔT =
= 47.85°C
To maintain the normal body temperature (98.6F = 37°C) the amount of heat released by metabolism activity must be utilized for evaporation of some amount of water
Hence
Note (1 kg = 1000 g)
This makes sense because firstly the value obtained is positive then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature
