You have a 1.0-cm 3 sample of lead and a 1.0-cm 3 sample of glass. You drop each in separate beakers of water. How do the volumes of water displaced by each sample compare? Explain. 15. Sketch a magnified view (showing atoms/molecules) of each of the following and explain: a. a heterogeneous mixture of two different compounds b. a homogeneous mixture of an element and a compound 16. You are driving 65 mi/h and take your eyes off the road for "just a second." What distance (in feet) do you travel in this time? 17. Consider the addition of 15.4 to 28.
