NEED ASAP THANK YOU!

Chemistry
1 answer:
Bezzdna [24]2 years ago
8 0

Answer:

d. 10

Explanation:

The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12

Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.

The confusing thing is that + means subtract and - means add here.

Hope this helps.

True or False Electrons are found in layers outside the nucleus.
Marina86 [1]

Answer: true

Viewed simply, electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy. Electrons further away from the nucleus will have higher energy. An atom's electron shell can accommodate 2n2 electrons (where n is the shell level).

Mars2501 [29]

The answer is yellow .

That is if you started blowing your exhaled air into a phenol-red containing solution, then it color will change to yellow.

It changes it color as we blow exhaled air into it as we are introducing carbon dioxide into the mixture.

And as carbon dioxide concentration increases, the H ion concentration increases that means the solution becomes acidic that is it becomes yellow.
