__H3PO4 + __Ca(Oh)2 --> __Ca3(Po4)2 + __H2O Balanced equation

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

a electronegativity decreases beacuse the size of nucleus is bigger.

consider the reaction below.
