The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].

The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.

After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.

The third one: [tex]CuSO_4[/tex]

Explanation:

Again you are going to want to look at a periodic table so you can determine the symbol of each atom.

The symbol for copper is Cu, the symbol for sulfur is S and the symbol for Oxygen.

There is 1 atom of copper in the compound

So we have Cu

There is 1 atom of sulfur in the compound

So we would have CuS

There are 4 atoms of oxygen in the compound

So we would have [tex]CuSO_4[/tex]

Note that the little number at the bottom left after each symbol indicates how many atoms of that element are in that compound.

The Newton's Second law of motion, also known as The Law of mass and acceleration, derives the given equation in terms of mass, acceleration and force.

It actually states that Force applied on a body is equal to the time rate of change of it's momentum.

Momentum of a body, is the product of it's mass and velocity with which its moving.

This clarifies that objects at rest have zero momentum since they have zero velocity.

If a "source" applies force on an object, it's magnitude would depend on its rate of change of momentum with time.

Since, mass of an object is a fixed entity, so change in momentum would be caused due to change in velocity.

Now, if we happen to have two objects of different mass,

(As, in here, a chair and a large couch) and we have to push them so as to produce the same change in momentum, the force applied on a couch would be more than that applied on the chair.

This is simply because,

Force = mass × acceleration

If acceleration for both the objects is fixed, the force applied differs due to theur difference in mass.

Note here that Force I'd directly proportional to mass.

The greater the mass is, the higher is the force required to produce same acceleration.

Thus, objects with higher mass will require a greater amount of force to have the same acceleration as the object of light weight.

The compound that has been capable to shift the equilibrium with common ion effect has been  [tex]\rm \bold{Na_2CO_3}[/tex].  Thus, option D is correct.

The complete equation for the decomposition of calcium carbonate has been:

[tex]\rm CaCO_3\rightleftharpoons Ca^2^+\;+\;CO_3^2^-[/tex]

The equilibrium has been the state in the reaction, when the number of products and has been equivalent to the number of reactants. The increase or decrease in the concentration of any of the reactant or product results in the shift in the equilibrium.

For the given reaction, the addition of Calcium or carbonate ions to the solution results in the increase in the product concentration with the common ion effect, and thereby shifts the equilibrium condition.

The ions liberated by the following compounds has been:

[tex]\rm CCl_4\;=\text{not dissolved}\\CO_2\;+\;H_2O\leftrightharpoons CO_3^-\;+\;H^+\\CuSO_4\leftrightharpoons Cu^2^+\;+\;SO_4^2^-\\Na_2CO_3\leftrightharpoons 2\;Na^+\;+\;CO_3^-[/tex]

The compound, that has been capable of liberating the carbonate ions in the medium has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, it results in the shift of the equilibrium due to common ion effect. Hence, option D is correct.

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.
