Consider the reaction h2so4 + 2 naoh -> na2so4 + 2h2o as it represents an acid-base tritration. the equivalence point occurs when 25.34 ml of 0.2767 m naoh is added to a 39.54 ml portion of h2so4. what is the molar concentration of h2so4 expressed in m?

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.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
