Well, all of this we owe it to Bohr who analyzed the atomic emission spectrum of hydrogen and he could probe matematically that it was a result of movement of e- from an especific energy level to a lower one. The understanding of levels of energy took to the development of the atomic theory
5g NaOH x 1 mol NaOH/ 39.99g NaOH = 0.125 mol NaOH
Answer:
H2O is the formula for water.
dissociation of proton from the acid depends upon the central atoms's electronegativity
More is the electronegativity of halogen ⇒ more is its pull on the oxygen ⇒ easier will the bond breakage of O-H ⇒ higher the acidity
In terms of E.N :
Cl > Br > I
so HClO₃ is highest acidity with the highest Ka value
The octet rule signifies towards the capability of the atoms to prefer to exhibit eight electrons in the valence shell. In case, when the atoms possess lesser than eight electrons, they seem to react and produce more stable components. While discussing octet rule, one does not consider d or f electrons.
According to the octet rule, the atoms of the prime-group elements seem to bind in such a manner that each atom exhibit eight electrons in its valence shell, providing it the similar electronic configuration as a noble gas.
In the given question, in BrF3, fluorine follows octet rule, while bromine does not follow the octet rule.
