<span>Hybridization is the chemist's attempt to explain the observed molecular shape by constructing HAOs with the appropriate inter orbital angels.
A molecule adopts its most stable shape all by itself ,then the chemist calculated what HAOs correspond to the shape.There is a One-to One correspondence between shape and hybridization.</span>

Answer:
The cause of periodicity in properties is the repetition of similar outer electronic configuration after certain regular intervals. For example, all the elements of group 1 i.e. alkali metals have a similar outer electronic configuration, ns1.
First convert mass to number of moles. Molar mass
of H2C2O2 • 2H2O = 94 / mol
1.89g / (94 g / mol) = .02 mol H2C2O2 • 2H2O
Then we divide by 0.1 L, or 100 mL, and we get a
concentration of 0.2 M.
Since there are two positive ions (2 H+), therefore
normality is:
