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☀️
The tendency of sound waves to bend when they pass from one medium to a different medium is known a refraction.
<h3>What is refraction ?</h3>
In diffraction, a sound wave is bent or stretched out in a single medium where the sound speed remains constant. Refraction is a crucial instance in which sound waves arc or diffuse. Due to variations in the wave's speed, a sound wave bends in this occurrence.
A wave bends as it travels along the edge of an object or through an aperture. It is referred to as diffraction. When a wave transitions from one medium to another at an angle, it also bends. It's known as refraction.
Thus, The option A is correct.

Answer:
136.5886g of NH3
Explanation:
N2 + 3H2 = 2NH3
The mass of the N2 = 4.01
3H2 has a 2/1 ratio
This means the mass of 3H2 is twice as much as N2.
NH3= 2*N2 = 2*4.01 = 8.02 of NH3
Then, by multiplying the mass by MX (17.031)
8.02*17.031=136.5886g can be produced. Round it if needed.
More water is not always better. For example; cacti only need water about every two weeks, the same with succulent plants. Not every plant needs to be watered every day, or the plant may be overwatered and die.
