A pyramid of energy is used to analyze the amount of energy available at each feeding level in a food chain. Using the pyramid a
bove, answer the question: Why is the amount of energy available to the tuna less than the amount available to the mackerel?
There aren't enough zooplankton
There aren't enough phytoplankton
While mackerel are getting energy, they are also using some of it.
If the tuna dies, the mackerel will eat it.

Explanation:
The reaction equation will be as follows.
Using bond energies, expression for calculating the value of is as follows.
On reactant side, from number of bonds are as follows.
C-C bonds = 1
C-H bonds = 6
From ; Cl-Cl bonds = 1
On product side, from number of bonds are as follows.
C-C bonds = 1
C-H bonds = 5
C-Cl bonds = 1
From HCl; H-Cl bonds = 1
Hence, using the bond energies we will calculate the enthalpy of reaction as follows.
= = -102 kJ/mol
Thus, we can conclude that change in enthalpy for the given reaction is -102 kJ/mol.
