Section 5: 5. Ammonia, NH3, is commonly used as a household cleaner. Often it is mixed with water to dilute it before cleaning begins, and water is used afterwards to rinse the cleaned area (floors, countertop, sink, shower). a. What is the molecular geometry (shape) of the NH3 molecule? b. Is NH3 polar or non-polar? How did you determine that? Mark the polarity on the NH3 molecule using the molecular dipole ALL PURPO moment arrow. c. Refer to the "like dissolves like" concept described in Section 4 above to explain why after cleaning floors with the household cleaner ammonia, NH3, then water, H,0, can be used to rinse the floors (the ammonia is able to dissolve in the water). CLE ARA Section 6: 6. Water is a good solvent for many things, particularly for charged ions and for polar molecules. Decide which of the following five compounds would most likely dissolv in water (see molecule structure below each name/formula): Table salt (NaCl) Benzene (C6H6) н H-czċ. H. NaCe H.
