Answer:
the result is C and D. those are the ansers
Answer:
The electrons in an atom move around the nucleus in regions known as electron shells.
1) Assume M refers to a general element and Z referes to other general element.
2) Assume the chemical formula of the ionic compound is MₓZₐ
3) Then the dissociaton would be written:
MₓZₐ → XMᵃ⁺ + AZˣ⁻
That means that the ionic compoud will lead to the X cations Mᵃ⁺ whose oxidation state are a+, and A anions Zˣ⁻ whose oxidation state is x⁻.
5) For example: MgBr₂ (aq) → Mg⁺² (aq) + 2Br⁻ (aq)
6) Explanation: since the water molecules are polar, they will surround (solvate) the three ions that form the compound MgBr₂, overcoming the electrostatic forces that hold together the atoms in the ionic lattice.
