"how many particles would one formula unit of alcl3 produce when dissolved in solution?"

Chemistry

I think you mean “atoms”
And it’s 4 atoms
True [87]3 years ago
3 0

Answer: 4


Justification:


1) The dissolution of a formula unit of AlCl₃ is given by the chemical equation:


AlCl₃ (s) → Al₃⁺ + 3 Cl⁻


So, 1 unit of AlCl₃ yields 1 partilce of Al₃⁺ and 3 particles of Cl⁻.


2) You get that through a mass balance and the oxidation states (balance of charge).


i) Mass balance: the same number of atoms of each species must appear on the reactant and the product sides.


ii) The oxidation state of Al is 3+ and the oxidation state of Cl is 1-, so the total net charge is 3+ + 3(1-) = 3 - 3 = 0.

Why are hydrogen bonds important for the properties of water?
zavuch27 [327]
Water has the special type of attraction called Hydrogen bonding.  The bonds between the Hydrogen and the Oxygen in each water molecule make a super dipole because the Oxygen atom is way more electronegative than the hydrogen atom.  These OH bonds can then be attracted to other H2O molecules.  If you have ever poured water up to the brim and there is  little bit of water that is poking above the top, hydrogen bonding keeps those water molecules from spilling

OLga [1]

Answer:

3- is the charge and 8 dots on its Lewis dot structure.

Explanation:

Hello there!

In this case, since nitrogen is an element with five valence electrons (electrons on its outer shell), we infer that it needs three bonds to complete the octet, for which its charge, when forming nitride ions is 3-, which means it has received three electrons. Thus, when drawing the Lewis dot structure, it is evident that is will have 5+3 = 8 dots due to the electron reception.

Regards!
