It would be CaF2 because you will need to balance then so since F is -1 it'll need another one to balance with Ca +2
Answer:
Explanation:
they both break down the earth
Answer:
The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
Answer: metal
Explanation: it says element so conductor and semiconductor are out and a halogen is a group of gases on the periodic table so this brings up to a conclusion of metal.

Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:

Where, the molar mass of each element are:


Calculating the molar mass of the compound, we have:


Now, calculating what is the mass of 6.78 of
, we have:

So, there are 732.24 grams of Dinitrogen Pentoxide
in 6.78 moles of the same compound.
Have a nice day!
