Number of neutrons = mass number - atomic number
= 15 - 9
= 6
The generic equation for a reaction between an acid and water is

When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base (

), and the conjugate acid-base pair is

-

.
Hydrogen sulfate (

) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water ((

) to form the sulfate (

) and hydronium (

)ions.

Based on the previous discussion,

is identified to be the conjugate of the acid

.
Thus, the conjugate acid-base pair is
.
Answer:
Cyclohexene doesn't exhibit this type of Isomerism. Cyclohexene is a tiny ring to exhibit the trans isomer. The Structural formula and component bonding characteristic within it limits it to show this phenomenon. Trying to force it to be trans would place a massive amount of ring strain on the molecule.
This characterises major rings within Alkene group up to cyclooctene.
