Explanation:
The specie produced when a strong acid is dissociated in water along with the proton is the conjugate base of that acid.
Consider a strong acid such as HCl which donates the proton so readily as it is a strong base and there is no tendency for conjugate base, which is
to re accept that proton.
A strong base is the one which accepts proton and holds it firmly. Thus, the strong acid has weak conjugate base.
1.7 km^2 already has two significant figures.
N=3^K-1 I really don't know how to explain it but that's the formula <span />
One molecule of N2O4 contains
two nitrogen
four oxygen
