It's not, if it were it would be ice. The water is a bit warmer.

Because the electrons in a solid, in this case the ice, are only vibrating. And so when it heats up, the electrons vibrate more. Imagine a scale from 1 to 150, 1 to 50 is a solid, 50 to 100 is a liquid, and 100 to 150 is a gas. If the ice has just been melted, then the electrons are only just in the beginning stages of moving enough to be a liquid, and the movement of electrons determines the temperature because it creates energy. I hope this was the answer you were looking for, let me know if I confused you

How many moles of oxygen atoms are in 1.2x10^25 diphosphorus pentoxide molecules
insens350 [35]

Answer:

19.9 atoms

Explanation:

Grams --- Moles --- Atoms

You're converting from atoms (molecules) to moles.

You do not have to calculate the mass of "di phosphorus pentoxide."

Since you're already given 1.2x10^25 atoms, you start with that. You need to cancel out the atoms, so you need Avogadro's number as shown in the image.

(This has nothing to do with the problem) But in case if you're wondering, the "di" in phosphorus means there's 2 phosphorus and the "pent" means that there are 5 oxygens. So P2O5. Go to your periodic table, multiply their respective atomic masses. You would multiply phosphorus twice and oxygen 5 times. And add them up to get the overall mass.

I hope this helped!
