Explanation:
[OH⁻] = 1.6 × 10⁻⁸ mol / dm³
<h3>Explanation</h3>
By definition,
, where
is the concentration of proton in the solution.
pH = 6.2 for this solution. As a result,
.
, where
the concentration of hydroxide ions and
is the dissociation constant of water.
at 0.10 MPa and 25 °C. As a result,
.
83.3 mL
Explanation:
M
= 3M
V
= 50mL
M
= 1.80M
Unknown:
V
= ?
Solution:
To solve this problem we must understand that the initial and final number of moles remains the same.
Number of moles = molarity x volume
Molarity x volume of initial solution = Molarity x volume of final solution
Therefore:
M
x V
= M
x V
M is the molarity
V is the volume
i = initial state
f = final state
input the parameters;
3 x 50 = 1.8 x V
V
= 83.3 mL

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.
