A student delivered 17.06 mL (V1) of 7.16 % stock solution (M1) using a graduated pipette into a 50.00 mL (V2) volumetric flask.

Distilled water was added to the flask to the graduation mark and mixed well.
Using the dilution equation (provided below), calculate the concentration of the diluted solution.

(M1)(V1) = (M2)(V2)

The concentration of the diluted solution will be 2.44%.

<h3>Dilution problem</h3>

From the equation of dilution:

(M1)(V1) = (M2)(V2).

where M1 = concentration before dilution, M2 = concentration after dilution, V1 = volume before dilution, and V2 = volume after dilution.

In this case:

V1 = 17.06 mL

V2 = 50.00 mL

M1 = 7.16%

M2 = ?

M2 = (M1)(V1)/(V2)

        = 7.16 x 17.06/50

               = 2.44%

Thus, the concentration of the diluted solution is 2.44%.

An atom has a mass number of 30 and 16 neutrons. What is the atomic number of this atom?
Lana71 [14]
The mass number is the number of protons plus the number of neutrons. Since there are 16 neutrons, there are 14 protons. This also corresponds to the atomic number, so this atom's atomic number is 14 which is also Silicon

g Where, approximately, is the negative pole on each of these molecules? Lewis structure for C O F 2. A central C atom is single
seropon [69]

The molecule with higher dipole moment is COFH because the geometry of the molecule in the COF2 nearly cancel the dipolar moment of each other. To be more clear:

The dipolar moment is the vectorial sum of all bond moments in the molecule or dipolar moment of each bond. The dipolar moment of a molecule with three or more atoms is determined by bond polarity as their geometry.

COF2 has a trigonal planar structure which are symmetric. The electronegativity of oxygen is slightly different regarding fluor. So as you can see in the image, the electronic density is specially displaced to the fluor atoms, but either to the oxygen atom.

COFH has a trigonal structure but differs from COF2 because there is an hydrogen who is donating it's electronic density, so in this zone the electronic density is less than over oxygen or fluor. That makes bond angles be different between them.

Answer:

BRAINLIEST?

Explanation:

Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. My findings said that ammonia is a weak base, potassium hydroxide is a strong base, vinegar is a weak acid and ethyl alcohol is a weak acid.

Vinegar and ethyl alcohol are eliminated as they are acids. The question is on bases.... Potassium hydroxide is a strong base. So we are left with ammonia, being a weak base.

A gas mixture contains oxygen, nitrogen, and carbon dioxide. It has a pressure of 250 mmHg. If the pressure of oxygen is 50 mmHg
kondor19780726 [428]

Answer:

P_{CO_2}=25mmHg

Explanation:

Hello there!

In this case, according to the Dalton's law, which explains that the total pressure of a gaseous system equals the sum of the partial pressures of the gases composing, for the gaseous mixture composed by oxygen, nitrogen and carbon dioxide it would be possible to write:

P_{tot}=P_{N_2}+P_{O_2}+P_{CO_2}

Now, given the pressure of the system and those of oxygen and nitrogen, we calculate that of carbon dioxide as shown below:

P_{CO_2}=P_{tot}-P_{N_2}-P_{O_2}\\\\P_{CO_2}=250mmHg-50mmHg-175mmHg\\\\P_{CO_2}=25mmHg

Best regards!

How does freezing affect the volume of water?
MrRissso [65]

Increases the volume of water

Explanation:

Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.

When ice freezes it expands and takes up more volume of space for the same mass given.

This is why bottles break when water in them is frozen.

This increase in volume is why ice floats on water. It makes it less dense.
