PRE-LAB QUESTIONS 1. Draw an electron dot diagram for methane. 2. Use Figure 9 and the periodic table (Figure 2) to construct a hypothesis about the melting points of stearic acid and sodium chloride. How will they compare, and how does that relate to the bonds that hold atoms in the compounds together? Figure 9: Structure of Stearic Acid Because of the statement that more that bonds are complex, the easier they are to break apart. The stearic acid will break apart easier while the sodium chloride has the simpler bonds and will therefore take longer to melt. Chemical Bonding

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
