That would be phosphorus. It’s electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^3
Hydrogen bonds are typically stronger than Van der Waals forces bc they are based on permanent dipoles, that form when hydrogen comes in vicinity of a highly electronegative atom (like F, N, or O). These bonds are long-lasting and pretty strong.
Somewhere in the Orange to red range
B.......it is believed that moon was formed because a huge body struck earth to break it and form moon......it can be proved due to geological similarities between earth and moon.
HOPE IT HELPED !!
nothing will happen
if you calculate the water potiential for both solutions
you get 2(0.1)(R)(T) and 1(0.2)(R)(T)
which is the same thing, so its isotonic.
