Cation a has a +3 charge and is small. cation b has a +1 charge and is large. which is more likely to occupy negatively charged sites on a clay mineral given equal concentrations in solution? cation a cation b they are the same

Correct Cation -A

Given that both the cations, cation-A and cation -B have the same concentrations.

Charge on cation-A is +3, while charge on cation- B is +1. Cations with higher charge can easily substitute those present on the clay minerals. Cations with higher charge have a greater affinity for the negatively charged sites present on the clay mineral. So, cation -A with a charge of +3 is more likely to occupy the anionic sites on the clay mineral.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
