Asolution has a ca2+ concentration of 0.049 m and an f- concentration is 0.147 m at equilibrium. the value of ksp for caf2 at 25°c is 4.0 x 10-11. will this solution form a precipitate? yes no

well in order to answer this question you have to provide more information < 3

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

there is none because earth is stationary and flat.
