Boron trifluoride (bf3 ) is used as a catalyst in many organic synthesis reactions. what type of bonding occurs between the atoms of a bf3 molecule?

Well, a covalent bond. A covalent or dative bonding is a chemical bonding that involves the sharing of electron pairs between atoms. It is usually occurs between two non-metal atoms trying to.obtain a stable outer electron. Atoms will covalently bond with other atoms to a obtain a full electron shell. Atoms obtain this stability by sharing their outer most electrons. A boron atom cannot reach the noble gas structure simply by sharing electrons. This isn't a disadvantage because the boron atom forms as many covalent bonds it can with the dissipation of heat.

Caso4(s) < > ca+2 + so4^-2 ksp = [ca+2][so4^-2] = 2.4 x 10^-5 = [0.20][so4^-2] [so4^-2] =1.2 x 10^-4 ag2so4(s) ,> 2ag+ + so4^-2 ksp = [ag+]^2[so4^-2] = 1.5 x 10^-5 = (0.30)^2[so4^-2] [so4^-2] = 1.5 x 10^-5/0.09 = 1.7 x 10^-4 caso4 would precipitate first since it requires less so4^- to form a saturated solution.  i believe this is right, i hope it !
