H2O has a higher intermolecular force (hydrogen bonding) where N2 only has London Dispersion.
In a controlled experiment the factor tested is called the experimental group
Ca<span>2+</span> is less electro-positive than Mg2+. Therefore, CaO is less ionic than MgO. and in turn means that the O in CaO is more like O<span>2<span>– will react with H in H2O more so than O2- of MgO, because it is more ionic means O is strongly bonded to Mg compare to Ca</span></span>
