When dissolved beryllium chloride reacts with dissolved
silver nitrate in water, aqueous beryllium nitrate and silver chloride powder
are made.
BeCl2 (s) + 2AgNO3 (aq) ---> Be(NO3)2 (aq) + 2AgCl(s)

To write the eqn, you need to know what number of atoms of
one element reacts with what number of atoms of another element. E.g. Be needs
to lose two electrons and chlorine needs one electron, hence, one Be atom
reacts with 2 Cl atoms.
