Explanation:
The given data is as follows.
Molecular weight of azulene = 128 g/mol
Hence, calculate the number of moles as follows.
No. of moles = 
= 
= 0.0030625 mol of azulene
Also, 
Now, putting the given values as follows.
= 11748.67 J
So, 
= 1886.4 J
Therefore, heat of reaction will be calculated as follows.
= (11748.67 + 1886.4) J
= 13635.07 J
As,
13635.07 J = 
dE = 
= 4452267.75 J/mol
or, = 4452.26 kJ/mol (as 1 kJ = 1000 J)
Thus, we can conclude that 
for the given combustion reaction per mole of azulene burned is 4452.26 kJ/mol.
Answer:
A
Explanation:
heat energy is transfered through a hot object touching a cold object
Answer: Option (a) is the correct answer.
Explanation:
A protein part of an enzyme is known as an apoenzyme. An apoenzyme combines with a cofactor, it is known as holoenzyme.
Without a cofactor an apoenzyme cannot function as cofactor helps in the formation of an active enzyme system and provides a specific site on enzyme for the substrate.
Whereas a non-protein chemical compound or metal ion that helps in the activity of enzyme as a catalyst is known as a cofactor. A metal ion cofactor can be bound directly to the enzyme or to a coenzyme.
The organic non-protein molecules which bind to the protein molecule to form an active enzyme is known as a coenzyme. Coenzymes are small size molecules which help the enzymes to act as a catalyst.
Therefore, we can conclude that the statement an apoenzyme can catalyze its reaction without its cofactor, is false.
