From the balanced molecular equation, write the complete onic and net ionic equation for the following:
(a)k2c2o4 + ba(oh)2 - > 2koh + bac2o2
(b)pb(no3)2 + h2so4 -> 2hno3 + pbso4
(c)caco3 + h2so4 = co2 + caso4 + h2o

Answer : The net ionic equation will be,

(a)

(b)

(c)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

(a) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

(b) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

(c) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, is the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.The net ionic equation will be,

1.cause they have wings

2.cause they are insects

3.cause they are

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
