You are a researcher studying the effects of "Compound X" on the soil microorganism Azotobacter vinelandii. You add "Compound X" to a flask of A. vinelandii with a concentration of 1x106 CFU/mL. After 5 hours, you assess the concentration of A. vinelandii in the sample and it is 1x106 CFU/mL. What term best defines "Compound X"?

Idon't hope someone you

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck

Cis the answer to your question

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 !
