Answer:
4 moles
Explanation:
A mole is equal to 6.02214076 × 1023 of any chemical unit (atoms, molecules, ions)
To find number of moles in 89 litres of water vapor use the following formula:
1 mole = 22.4 L
That is 1 L =
mole
Volume of water vapor = 89 litres
Therefore,
Number of moles in 89 litres =
≈ 4 moles
I think the answer would be : Tetrahedral
Oxygen has 6 electrons and need 2 more electron to complete its octet. In Tetrahedral, the electrons are arranged so it surround the oxygen and forming a 109 degree bond angel/
hope this helps
I forgot this one, but I learned this in physics class. It had something to do with there being more or less electrons for how ever many photons there is in an atom.
Example: Hydrogen has 1 photon which usually means there is one electron, but when there is more electrons than photons, that is a negative ion. When there's less electrons than photons, that is a positive ion.
