While exploring an ancient lava field, a geologist discovers a piece of granite that has a coating of soft, crumbling rust. What

is the most likely explanation for this rust?
A.
Exposure to air has caused the iron-bearing minerals in the granite to oxidize.
B.
At some point in the past, a river flowed over the field, depositing the rust on top of the granite.
C.
Exposure to acid precipitation has worn away the granite's exterior, revealing its soft interior.
D.
Snails and fungi living in the lava field have secreted chemicals that reacted with the granite to form rust.

Answer:

A. Exposure to air has caused the iron-bearing minerals in the granite to oxidize.

Explanation:

The main cause of granite rust is a metal substance that remains in it's contact over a long period of time. As a result of a moist or wet environment, . a geologist discovers a piece of granite that has a coating of soft, crumbling rust.

Exposure to air has caused the iron-bearing minerals in the granite to oxidize.

Option A. is correct.

s344n2d4d5 [400]

Answer:

Being a weak acid and a strong base, where it is diluted in a neutral medium such as water, the basic medium predominates, almost alkaline pH.

Explanation:

The acidity of the solution, being weak, means that its pH is not so low, therefore it will be easier to reach the values of 7 or 7 where alkalinity or basity is indicated.

What is the affect of neutrons on atoms
Evgen [1.6K]

Answer:

It's better to explain it.

Explanation:

Neutrons do not affect the electron configuration, but the sum of atomic number and the number of neutrons, or neutron number, is the mass of the nucleus. You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together. if your asking What is the role of a neutron in an atom? then, Neutrons are very important in providing stability for an atom. Some atoms don't "need" neutrons - The hydrogen atom does not have any neutrons. However, as the atomic number ( # of protons ) increases, the number of neutrons increases as well.

Protons don't like each other. Naturally, 'positive charges repel', so it wouldn't be possible to have more than one proton in the nucleus. Here's where the neutron comes in.

Hope this helps. :)

What is the pH of a solution with hydrogen ion concentration of 1 x 10^–6 M?
kakasveta [241]

Answer:

The pH of the solution is 6,00.

Explanation:

The pH indicates the acidity or basicity of a substance. pH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:

pH = -log (H +)

pH= -log (1x10^-6)

<em>pH= 6, 00</em>
