<span>A spectator ion is an ion that exists in the same form on both the reactant and product sides of a chemical reaction.</span>
I would sat the answer will be condensation if that's one of your choices
False-- most of the time not enough energy is put into the system, so the compounds or whatever cant break down fully into their elements
Explanation:
The answer would be B.
As paramagnetic with 3 unpaired electrons. Since there are 6 ligands around the Co+2 ion it isoctahedral and these ligands are neutral. This makes the overall charge on the complex +2 and therefore comes from the configuration for Co+2 which is [Ar] 3d7. Since it is in high spin you must fill all the orbitals with at least one electron and then pair up any that remain. If you do this, 3 unpaired electrons remain. Para magnetism occurs in substances with unpaired electrons.
Weathering would be chemical because it's more natural than physical
