I need help ASAP please<br> Calculating pH<br> See chart below
laila [671]

Answer:

12, basic, 9, basic

Explanation:

pH = -log[H+]

Using the data in the table, you can calculate the pH:

-log[1e-12] = 12

-log[1e-9] = 9

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.

What is the orientation of the two unhybridized p orbitals on Be with respect to the two Be−F bonds?
Len [333]

Answer:

b) Both p orbitals are perpendicular to the F−Be−F bond axes.

Explanation:

Be has 2 electrons in its valence shell, subshell s is fulfilled, so it has no unpaired electrons in its ground state to make bonds with F. So, it can promote the electrons to the 2p orbital and will having sp hybridization.

The bond between the orbitals sp and the p orbital of F are in opposite directions but the same ax. The two bonds are equivalent, and the molecule had a linear geometry. The two unhybridized p orbitals on Be are vacant, and so they are perpendicular to the F-Be-F bond axes.
