Look at the structure of a soap molecule, and explain what happened when you added soap to your oily hands and put your hands under the water for the solubility lab. Why could you wash the oil off your hands with soap and water? You should use chemistry concepts including structure, polarity, and intermolecular forces to explain your answer. attached is the lewis structure of a basic soap molecule. There are covalent bonds between all carbons, hydrogens, and oxygens. However, there is an ionic bond between oxygen and sodium ions.

Does NaCl(s) conduct electricity at room temperature?  Yes/No and Explain why?

Using the patterns evident in a table of electronegativity values, K has a higher electronegativity relative to Ca. True or False True False

Draw a water molecule and show the partial charges. Explain why water has a partial charge.

we would predict that the imaginary ionic compound XF would have a (higher /lower) lattice energy than YyF2 because

Consider the element Work (Wr) with an atomic number of 33 and an atomic mass of 81.03 g/mol. The following information was collected for this element  Molecule/ Ion Names Wr-2 Workide WrO3-2 Workate WrO2-2 Workite WrO-3 hydroworkite   Draw the Lewis structure of the molecule Workous acid and determine its electron geometry and molecular geometry. What is the mass % of work in Calcium hydroworkite.

Understanding electrostatic forces. Choose where the object outlined in green will go based on the charges.

Use Lewis dot symbols to show the formation of magnesium oxide.

Predicting whether molecules are polar or nonpolar.

2. Sulphur reacts with oxygen to form sulphur trioxide through sulphur monoxide and sulphur dioxide. Sulphur trioxide reacts with water to form sulphuric acid. Balance the equations for the above and draw the Lewis structures for each of the oxides and the acid. next page
