Chemistry
1 answer:
laila [671]3 years ago
5 0

Answer:

12, basic, 9, basic

Explanation:

pH = -log[H+]

Using the data in the table, you can calculate the pH:

-log[1e-12] = 12

-log[1e-9] = 9

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.

Which type of van der walls force is responsible for holding polar molecules together? london dispersion dipole-dipole hydrogen
svet-max [94.6K]

Answer:

dipole-dipole

Explanation:

Polar molecules are formed as result of covalent bonds between atoms.

Dipole-dipole attraction are intermolecular bonds. Both London dispersion forces and dipole-dipole attraction are van der waals forces.

In dipole-dipole attraction, polar molecules (unsymmetrical molecules) line up such that the positive pole of one molecule attracts the negative pole of another. Example of such is found in HCl.

Explain how a redox reacation involves electrons in the same way that a neutralization reaction involves protons
lidiya [134]
For the neutralization process: an acid acts as a donor and donates protons to the base. On the other hand, the base acts as an acceptor and accepts the transferred protons. In a nutshell, neutralization is mainly proton transfer process.

As for the redox process: the oxidized material usually transfers electrons to the reduced material. In a nutshell, redox is mainly electron transfer process.

How does wind cause weathering?
pantera1 [17]

Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!

The answer to your question is

D) Blowing sand can wear away a rock's surface and break it into smaller pieces

When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.

Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.

I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.

Please give me brainliest if I was correct and helpful!

Otherwise, please comment and let me know how I can fix my answer!

Thank you, it was fun, have a nice week!
