Only Number 6 NOT GRADED!!
Öxidation half-reaction: Reduction half-reaction: Spectator ion(s) (if none, write none): 6. For the below problems consider a 0.123 M MgCl2 solution. A. Calculate the mass of MgCl2 needed to make 60.0 mL of this solution. B. Calculate the amount of water that is required to dilute this solution to 0.050 M. 7. Isopropyl alcohol, C3H8O, can undergo decomposition in the presence of the catalyst to give a C2H6O, and H2 according to the below reaction. C3H$O(1) C3H,0(1) + H2(g) If 25.6 mL isopropyl alcohol fully decomposes, what mass of H2 is formed? (The density of i. alcohol is 0.785 g/mL.)
