28 molecul are in mol of ox
Answer:
A new element
Explanation:
As you add mopre and more protons and electrons and neutrons it keeps on crating new.
It is more difficult over easy. Since you haven't figured it out and came here to ask.
Given that Ka = 4.3 × 10^-4
At the half equivalence (Stoichiometric) point;
pH = pKa = - log (Ka)
Therefore; pKa = - log (4.3 ×10^-4)
= 3.37
Therefore; the pH at the half-stoichiometric point is 3.37
Answer:
He2 molecule contains 4 electrons. Each atom gives 2 electrons in 1s orbitals. This way 2 (1s) orbitals combine to give 2 molecular orbitals viz. ... This indicates that there is no bond formation between 2 HE atoms and hence the He2 molecule does not exist.
