(a)
Interpretation:
The balanced equation needs to be determined for the complete combustion of compound octane
Concept Introduction:
A hydrocarbon undergoes combustion in the presence of oxygen to produce carbon dioxide and water.
(a)
Answer to Problem 54A
The balanced equation is
Explanation of Solution
Step 1:
It is known that when reactants are hydrocarbons in a combustion reaction, the products will be water and carbon dioxide. Thus, the equation becomes as
Further, according to the law of conservation of mass, the mass of the product must be equal to the mass of reactants. So, on the right side of the equation
Thus, the equation becomes:
Step 2:
Now, further on the left side of the equation
Thus, the equation becomes now as:
Hence, the balanced chemical equation is:
Or,
(b)
Interpretation:

(b)
Answer to Problem 54A
The balanced equation is
Explanation of Solution
Step 1:
The given reaction is as follows:
Further according to the law of conservation of mass, the mass of the product must be equal to the mass of reactants. So, on the right side of the equation
Thus, the equation becomes:
Step 2:
Now, further on the left side of the equation
Thus, the equation becomes:
Hence, the balanced chemical equation is
(c)
Interpretation:
