(a)
Interpretation:
The of water at given temperatures should be determined.
Concept Introduction:
: The concentration of hydrogen ion is measured using
scale. The
of a solution is a figure that expresses the acidity or the alkalinity of a given solution.
It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.
If the value of is less than
, then the solution is acidic whereas if the value of
is greater than
, then the solution is basic.
(b)
Interpretation:
The at given temperature should be determined.
Concept Introduction:
Ionic-product constant for water: It is the hydronium ion concentration times the concentration present in the solution.
The will apply to all aqueous solution.
For acidic solution is large that is
For basic solution is large that is
(c)
Interpretation:
The dissociation of water should be identified that whether it is an exothermic or endothermic reaction.
Concept Introduction:
Endothermic reaction: The reaction is considered as endothermic when heat energy is absorbed from surroundings during reaction.
Exothermic reaction: The reaction is considered as endothermic when heat energy is released to the surroundings during reaction.

This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon.
