Water goes into the sky by condensation I think
We are told we have an oxyacid of the formula HOFO. We will assume the atoms are in this order and will draw a proper lewis structure for this compound by first drawing bonds between each of the 4 atoms and then place the remaining electron pairs on each atom:
.. .. ..
H - O - F - O:
·· ·· ··
We can calculate the formal charge of an atom using the following formula:
Formal charge = [# of valence electrons] - [# of non-bonded electrons + # of bonds]
H: Formal charge = [1]-[0+1] = 0
O: Formal charge = [6]-[4+2] = 0
F: Formal charge = [7]-[4+2] = +1
O: Formal charge = [6]-[6+1] = -1
As we can see the overall charge of the molecule is neutral since the fluorine as a +1 charge and the oxygen a -1 charge.
Answer:
Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions
Explanation:
Common salt (sodium chloride) is one of the best-known ionic compounds. Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding).
The temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.
Food should reach a temperature serving 135°F before it can be opened in the restaurant and warmed for hot holding. Within two hours, quickly reheat the food. If food is being served right away, it can be served anywhere at temperature as long that it as it was cooked and chilled appropriately.
TCS food must be totally chilled to 41°F or even below in 6 hours after being thoroughly cooled between 135°F to 70°F in 2 hours. Within four hours, TCS food made with ingredients at room temperature needs to be chilled to 41°F or lower.
Therefore, the temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.

In ionic bond there is the formation of ions due to transfer of electrons from one atom<span> to </span>the other. Normally, at this link, there is an element that tends to yield electrons (metal-cation), and one that tends to receive electrons (not metal-anion).
Note: the Ionic bond is the only in the transfer of electrons<span>.</span>
