PLS HURRY MY TEST IS TIMED Question 7(Multiple Choice Worth 5 points)
(08.04 LC)
A low explosive is one that
ignites instantaneously
has a small explosive radius
decomposes slowly
uses little or no oxygen

Is there a picture or answer choices?

Qand k are only the same when the forward rate of the reaction has reached zero.

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 !  

The answer is a i hope it ! and if you want me to explain let me know !
