PLS I NEED HELP ASAP! BRAINLIEST TO FULL ANSWER!! The chocolate in your favorite candy bar has the chemical formula: C7H8N4O2. What elements are present in this formula? How many atoms of each element are in this molecule? Using some of the trends that you described in question 2, what patterns do you notice between these elements on the periodic table?

Carbon, hydrogen, nitrogen, oxygen
Carbon7 hydrogen8 nitrogen4 oxygen2

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 !
