The pH of a .1 M solution is 11. What is the concentration of H3O ions, in miles per liter

Answers

Answer 1

Answer: pH=-log[ H₃O⁺] therefore [H₃O⁺]=10^-pH
[H₃O⁺]=10^-11
[H₃O⁺]=1.0x10^-11

What statement is TRUE about the subatomic particles within an atom?a

Protons and electrons have the same mass.

b

Protons have a positive charge and are found in the nucleus.

c

Neutrons are negative and are found outside the nucleus.

d

Electrons are negative and are found in the nucleus.

Answers

The statement which is true about the subatomic particles within an atom is as follows:

Protons have a positive charge and are found in the nucleus.

Thus, the correct option is B.

What are subatomic particles?

Subatomic particles may be defined as those particles that significantly compose an atom. Such particles are generally smaller than atoms. In other words, it can be said that the subatomic particles are united together to form any atom.

Protons are positively charged subatomic particles that are found in the nucleus of an atom. Electrons are negatively charged subatomic particles that are significantly revolving around the nucleus of an atom.

Neutrons do not have any charge, they are neutral and are found in the nucleus of an atom along with protons.

Therefore, the correct option for this question is B.

What can be said about the polarity of the C=O bond? A) C and O have the same electronegativity; the bond is nonpolar B) the C=O bond is polar; the O atom bears a partial negative charge C) the C=O bond is nonpolar; the C atom bears a partial positive charge D) the C=O bond is polar; the C atom bears a partial negative charge

Answers

Answer:

The correct answer is B) the C=O bond is polar; the O atom bears a partial negative charge.

Explanation:

In a C=O bond, the oxygen (O) atom is more electronegative than the carbon (C) atom. Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. Oxygen has a higher electronegativity than carbon, so it pulls the shared electrons in the C=O bond closer to itself.

As a result, the oxygen atom gains a partial negative charge (δ-) because it has a higher electron density around it, while the carbon atom gains a partial positive charge (δ+) because it has less electron density around it.

This uneven distribution of electron density in the C=O bond leads to polarity, making the bond polar. The oxygen atom, being more electronegative, attracts the shared electrons more strongly, creating a partial negative charge on the oxygen atom and a partial positive charge on the carbon atom.

In summary, the C=O bond is polar, and the oxygen atom bears a partial negative charge (δ-).

A chemistry student must separate should barium sulfate from the aqueous solution.

Be sure to list the lab equipment needed to do the procedure
Explain how each item is used in the procedure
List any safety equipment needed and how it is used in the procedure
Describe how this procedure might be used in a situation outside the chemistry classroom

If there's just some barium put in an aqueous solution, then it should be something like this.
It's a mixture of a solution and an insoluble solid, so the easiest way to go is through filtration. (Also, I'm assuming the barium is cut into very small chips.)

In a line, simply filter the solution using a folded filter paper in a funnel, collect the residue in a beaker or flask, rinse it with distilled water and let it dry. (Or simply filtering it could be enough, depending on how far your teacher wants you to go.)

Stuff needed:
>filter paper (for separating the solid from the solution)
>funnel (to hold the filter paper)
>beaker or flask (to hold the filtrate)
>distilled water (to rinse the solid)
>spatula (to scoop up the solid)

Procedure:
>Fold filter paper and line the funnel with it. Place the funnel in the flask or beaker.
>Pour solution in. Then add water (I think using tap water might be fine in this case, but you can use distilled water if you'd like) to wash out the container with the solution of any solid you may have not gotten in the first try. Alternatively, you could use a spatula to spoon it onto the filter paper.
>Once everything has been filtered, pour some distilled water on the residue on the filter paper to wash away the solution.
>Take out the filter paper, open it up and let it dry.

This can be used in real life in many occasions. For example, when you make tea, you need to filter the leaves out. Or when you cook the pasta, you put it in a sieve to separate the pasta from the water. Or when you fish using fishing nets, you "filter" the fish from the water.

How many moles of I2 are in 8.23 moles of NaI ?

Answers

Answer: 4.12

Explanation:

we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.

8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2

we placed NaI at the bottom to cancel out with the 8.23 mol of NaI
