pH = -log([H+])

Therefore, 10^(-pH) = [H+]

[H+] = 4.57x10^-3

We must remember that negative energies (in any context) generally represent energetically stable configurations and as the energy of a system increases, it will become more unstable.

Firstly, ioni...

First it is important to know the molecular formula for pentane and the products of the combustion reaction so that we can write the unbalanced equation. From the prefix 'pent' we know that the hydrocarbo...

The electronegativity is the tendency of an atom to attract electrons towards itself in a covalent bond.

The electronegativity of the halogens decreases down the group as the radius of each atom in...
