This is an incomplete question, here is a complete question.
For each reaction, identify the Bronsted-Lowry acid, the Bronsted-Lowry base, the conjugate acid, and the conjugate base.
Express your answers as a chemical expressions. Enter your answers in order given in the question separated by commas.
Answer : The given equilibrium reaction will be,
Acid Base Conjugate Conjugate
acid base
Explanation :
According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.
Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.
The given equilibrium reaction will be,
Acid Base Conjugate Conjugate
acid base
In this reaction, is an acid that donate a proton or hydrogen to
base and it forms
and
are conjugate base and acid respectively.

Answer:
Part A
The volume of the gaseous product is
Part B
The volume of the the engine’s gaseous exhaust is
Explanation:
Part A
From the question we are told that
The temperature is
The pressure is
The of
The chemical equation for this combustion is
The number of moles of that reacted is mathematically represented as
The molar mass of is constant value which is
So
The gaseous product in the reaction is and water vapour
Now from the reaction
2 moles of will react with 25 moles of
to give (16 + 18) moles of
and
So
1 mole of will react with 12.5 moles of
to give 17 moles of
and
This implies that
0.8754 moles of will react with (12.5 * 0.8754 ) moles of
to give (17 * 0.8754) of
and
So the no of moles of gaseous product is
From the ideal gas law
making V the subject
Where R is the gas constant with a value
Substituting values
Part B
From the reaction the number of moles of oxygen that reacted is
The volume is
No this volume is the 21% oxygen that reacted the 79% of air that did not react are the engine gaseous exhaust and this can be mathematically evaluated as
Substituting values
