Atomic mass..so the answer is D
1st balance C : C5H12 -> 5CO2
2nd balance H: C5H12 -> 6H2O
final balance O : (5x2+6)/2=8 -> 8O2
So answer is: C5H12+ 8O2 -> 5CO2+ 6H2O
The correct name of the compound is 4-chloro-1-cycloheptene according to IUPAC nomenclature.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature is a system of naming compounds that was put together by the international union of pure and applied chemistry. The system enables the structure of a compound to be easily written from its name.
For the compound shown in the image attached to this answer, the correct name of the compound is 4-chloro-1-cycloheptene according to IUPAC nomenclature.

A) Anode - hydrogen gas
Cathode-oxygen gas
B) Hydrogen gas - The gas burns with a pop sound
Oxygen gas - The gas rekindles a glowing splint
C) The volume of gas produced at the cathode is 23
<h3>What is electrolysis?</h3>
Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The electrolysis of water produces two volumes of hydrogen at the anode and one volume of oxygen at the cathode.
The hydrogen gas burns with a pop sound. It is easily identified by this test. Also, oxygen is known to rekindle a glowing splint and this is a commonly used test for oxygen gas.
Since the ratio of hydrogen produced at the anode to oxygen produced at the cathode is 2:1 by volume; then when 23 of oxygen is produced at the cathode, 46 of hydrogen is produced at the anode.

Answer:
a. True
Explanation:
Yes, the titration curve can determine or can reveal the pKa value of a weak acid.
Titration is a scientific method to estimate the dissolved substance concentration, known as the titrand, in a known volume when it reacts with another chemical substance of known volume as well as concentration. The other substance is known as Titrant.
When a weak acid like acetic acid is titrated to a very strong base such as NaOH, the titration curve is obtained and the pH value is noted. But the titration curve of any weak acid shows a characteristic shape. At the end of titration, the acetic acid will convert into acetate ions.
pKa is the negative logarithm of the Ka of the acid. pKa is the pH of the acid where the concentration of the weak acid as well as the conjugate base is in equimolar concentration.
