An atom of fluorine has an atomic number of 9 and an atomic mass of 19. The atom contains
muminat
The number of neutrons is the difference between the mass number and the number of protons. 

You get the element by looking at the atomic number which is the number of protons. In this case, it is 9 and yes, it is F. 

<span>However it is not an atom because it has 10 electrons so you have a fluoride ion F-. </span>

<span>The number of neutrons = 19 - 9 = 10

Therefore, the answer is D.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Calculate the pH and pOH of 0.010 mol OH- per liter
Sati [7]
We can use a variety of formulas to determine our answers here.

Our formula for pOH is -log(mol), and we can plug it in as -log(0.010). Take note that OH- is a base, not an acid. 

So, the pOH of OH- is 2.

To find pH we can set up this simple equation:
pH + pOH = 14
All we need to do is subtract 2 from 14, therefore the pH is 12.

This makes sense since acids range in the pH of 1-6, and we are dealing with a base. Hope I could help!

MgSO4 x 7H2O:
natka813 [3]

Answer:In regards to writing the formula, we know that magnesium has a charge of 1+ and sulfate, SO4, has a charge of 1-. Sulfate is a polyatomic ion so the charge of the whole thing is (SO4)1-. When you combine them you end up with MgSO4 and the "heptahydrate" is seven water molecules.
