Answer:
See explanation and image attached
Explanation:
When 1 mole of hydrogen is added to 3-hexyne, the addition occurs on the same face or side of the triple bond to yield cis-2-hexene in the presence of lindlar catalyst which prevents further hydrogenation. This is known as syn addition.
The syn addition is achieved because the hydrogen molecule is first adsorbed on the surface of the palladium metal and is subsequently attached to the same face of the triple bond in 3-hexyne as shown in the image attached to this answer.
Answer:Chromatography technique that uses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass is called paper chromatography. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper.

Answer:
[H⁺] = 3.02 x 10⁻¹⁰M
Explanation:
Given parameters:
pH of the solution = 9.52
Unknown:
Concentration of the solution
Solution
There is a relationship between the pH and concentration of a solution.
pH = -log₁₀[H⁺]
The unknown here is [H⁺],
Now making it the subject of the formula
[H⁺] = Inverse log₁₀(-pH)
[H⁺] = Inverse log₁₀(-9.52)
[H⁺] = 3.02 x 10⁻¹⁰M
