Answer:
In the 1H NMR spectrum of ethanol three different signals are observed, this is due to the existence of 3 types of hydrogens with different chemical environment. Hydrogens A (3.57 ppm) are more screened than C (1.10 ppm) due to the presence of oxygen (electonegative atom that removes electron density). The chemical environment of hydrogen B (4.78 ppm), attached directly to oxygen, is also different by resonating at a frequency different from the previous ones.
The hydroxylic hydrogen produces a singlet, the pair of carbon hydrogens one give rise to a quadruplet and the three hydrogens of carbon two produce a triplet.

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
