Answer:
p
H
≈
11.5
Explanation:
When put in water, the
K
O
H
dissolves into
K
+
and
O
H
−
ions, with the latter increasing the
p
H
of the solution.
As hydroxides can be considered strong bases, it will completely dissociate into the water solution, and form an equal amount of moles of hydroxide ions:
0.003 mol of
O
H
−
.
Now,
p
O
H
=
−
log
[
O
H
−
]
p
O
H
=
2.522
And if we assume this is done under standard conditions:
p
O
H
+
p
H
=
14
p
H
=
14
−
2.522
p
H
≈
11.5
Hope it helped
Have a nice day☀️
I think it is B for the answer
Because you don't want glass jars because they will break. Plastic containers is the best thing to use
Answer:
% of n-propyl chloride = 43.48 %
Explanation:
There are 2 secondary hydrogens and 6 primary hydrogens
The rate of abstraction of seondary hydrogen = 3.9 X rate of abstraction of primary hydrogen
probability of formation of isopropyl chloride = 3.9 X 1 (relative rate X relative number of secondary hydrogens)
Probability of formation of n-propyl chloride = 1 X 3 (relative rate X relative number of primary hydrogens)
Total probability = 3.9
% of n-propyl chloride = 3 X 100 / 6.9 = 43.48 %
Due to the law of conservation of mass, _g K + 16g O=94g KO.
So, 94-16=78
78 is your answer
