A. An ion with a quadruple positive charge (4+) with an electronic configuration of [Xe] 4414 5010 State the orbital(s) where the electrons were removed from. Is this a stable ion? If so, why? If
not, why not?
b. An ion with a double positive charge (2+) with an electronic configuration of 1s 2s 2p 3s2
3p 3d7. Could an ion(s) of a different element have this same exact electron configuration?
Explain. If so, which ion(s)?
c. The full electron configuration for an ion of zinc.
d. A stable ion with the same number of unpaired electrons as Cr2+. How many electrons are
unpaired in these ions?

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
