Explanation:

The lewis dot structure or electron dot structure is a notation that shows only the chemical symbol of the element surrounded by dots to represent the valence electrons.

The chemical symbol represents the nucleus and all electrons except the valence electrons.
The dots are arranged at the four sides of the symbol pairs called lone pairs.
Those that are unpaired are called odd electrons.

What is the pH of a 0.033 M KOH solution

Natalija [7]

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
[

]

p

=
2.522
And if we assume this is done under standard conditions:
p

p
H
=

p

−
2.522

p

Calculate the volume in milliliters of a iron(II) bromide solution that contains of iron(II) bromide . Round your answer to sign

miv72 [106K]

This is an incomplete question, here is a complete question.

Calculate the volume in milliliters of a 1.29 mol/L iron(II) bromide solution that contains 275 mmol of iron(II) bromide . Round your answer to significant 3 digits.

Answer : The volume of iron(II) bromide solution is, $2.13\times 10^2mL$

Explanation : Given,

Concentration of iron(II) bromide = 1.29 mo/L

Moles of iron(II) bromide = 275 mmol = 0.275 mol

conversion used : 1 mmol = 0.001 mol

Now we have to calculate the volume of iron(II) bromide.

$\text{Volume of iron(II) bromide}=\frac{Moles of iron(II) bromide}}{\text{Concentration of iron(II) bromide}}$

Now put all the given values in this formula, we get:

$\text{Volume of iron(II) bromide}=\frac{0.275mol}{1.29mol/L}=0.213L=2.13\times 10^2mL$

Thus, the volume of iron(II) bromide solution is, $2.13\times 10^2mL$
