Gen Chem Exam 3 Questions And Answers 2024 (A Graded Solution) What compounds are soluble? - ANS-Group 1 ions and all nitrates (NO3-) Calculate the solubility of Sr(SO4-)2 How would you approach this problem? - ANS-First, write out the Ksp for this specific compound. So, Ksp = [Sr2+][SO42-]^2, Then, ICE table, +s and +2s, and that = 4s^3. That equals given Ksp How do you figure out if a precipitate will form? - ANS-Calculate Qsp. This is done by multiplying the given ion concentrati...

UNE Gen Chem 2 Midterm- Exam with Correct Answers 1. An adhesive force: is the result of intermolecular forces that attract different molecules together 2. Metallic solids: are composed of atoms, with nuclei in a "sea" of delocalized electrons 3. Acetonitrile, CH3CN, is a common solvent used in organic chemistry labs. Acetonitrile evaporates very quickly at room temperature and feels noticeably cold when evaporating. If ”H vap for acetonitrile is 34.2 kJ/mol, how much heat is removed wh...
