(45 points) Work out the following problems (12, 13, and 14) on paper. When you are done, take a photo of your work and upload it to CANVAS as a SINGLE jpeg or pdf. You must SHOW ALL OF YOUR WORK (no work – no points). You also must show ALL relevant reactions (equilibria and/or 100% complete). Report answers to three significant figures. Circle your final answers. Determine the molar solubility of silver sulfide, Ag2S, in a solution that is 1.5×10–4 M AgNO3. The Ksp of silver sulfide is 6.2×10–30. Determine the change in entropy for the following reaction using the entropies of formations given: 2 Pb(s) + O2(g)
