0 Exam 2 Practice Questions 1. A chemist is trying to determine the reaction order of the reaction she is conducting in lab. She remembers from her general chemistry class that a straight-line plot can be used in this situation. How would she plot her data to determine if the reaction is first order? What would be the x- and y-axis, the slope of the straight line, and the y-intercept? 2. The chemist from question 1 then determines that her reaction is actually first order. Her next step is to determine the half-life. What equation will she use to do this? 3. What is the name of a colloid produced by a gas dispersed in a solid? Give an example of such a material. 4. After a bad ice storm a chemist is trying to determine the best way to melt the ice on his sidewalk. Being a true scientist at heart, he is thinking in quantities of moles. Would it be more effective to use 1 mole of NaCl, or 1 mol of CaCl 2 ? Why?

    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.

    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.
