Answer:

The correct answer is option C.

Explanation:

When fan starts the fan blades also starts spinning around axle.The axle represent the nucleus and the uniform donut like shape(with slightly fade color) formed by the movement of blades represents the electron cloud around the nucleus.

Schrodinger proposed the quantum mechanical model of the atom in which he defined the location of electrons inside an atom by electron cloud in 3-d space (as shown in the figure).

Write balance complete molecular equation, ionic equation, and net ionic equations for the reactions that occur when each of the

AveGali [126]

<u>Answer:</u> The complete molecular, ionic, and net ionic equations are given below. The spectator ions are sodium and nitrate ions.

<u>Explanation:</u>

The ionic equation is defined as the equation in which all the substances that are strong electrolytes present in an aqueous state and are represented in the form of ions.

The net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.

The balanced molecular equation for the reaction of lead (II) nitrate and sodium sulfide follows:

$Pb(NO_3)_2(aq)+Na_2S(aq)\rightarrow PbS(s)+2NaNO_3(s)$

The ionic equation follows:

$Pb^{2+}(aq)+2NO_3^-(aq)+2Na^+(aq)+S^{2-}(aq)\rightarrow PbS(s)+2Na^+(aq)+2NO_3^-(aq)$

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

$Pb^{2+}(aq)+S^{2-}(aq)\rightarrow PbS(s)$
