Answer:
A. Berryllium is a paramagnetic
Answer:
Explanation:
Hello,
In this case, given the acid, we can suppose a simple dissociation as:
Which occurs in aqueous phase, therefore, the law of mass action is written by:
That in terms of the change due to the reaction's extent we can write:
But we prefer to compute the Kb due to its exceptional weakness:
Next, the acid dissociation in the presence of the base we have:
Whose solution is which equals the concentration of hydroxyl in the solution, thus we compute the pOH:
Finally, since the maximum scale is 14, we can compute the pH by knowing the pOH:

The mineral is calcite.
Lustre — glassy; ∴ non-metallic
Hardness — between a fingernail (2.5) and a penny (3)
Streak — white
Specific gravity — 54/20 = 2.7
Colour —white
Acid reaction — Fizzes; ∴ a carbonate
The only carbonate mineral that satisfies all these criteria is calcite, CaCO₃.
