Question:
Characterize each of the following using as many of the words from question 1 as applicable: Ne,
O2, NO2, air (consists of N2, O2, and a few other types of matter), salt water (NaCl and H2O).
Answer:
Ne: atom, element, pure substance O2: molecule, element, pure substance NO2: molecule,
compound, pure substance Air: homogenous mixture Salt water: homogenous mixture
Question:
Characterize each of the following as a physical property or chemical property:
Answer:
boiling point (physical) tendency to rust (chemical) density (physical) luster (physical) reactivity
with acid (chemical)
Question:
Characterize each of the following as an intensive property or an extensive property:
Answer:
heat content (extensive) reactivity with oxygen (intensive) mass (extensive) volume (extensive)
density (intensive) odor (intensive) melting point (intensive)
Question:
Circle the correct answer in each case: I am making a candle. I start by melting some white wax in a
pot. This is a (physical / chemical) change. I then add some red food coloring and stir. I have made
a(n) (element / compound / homogenous mixture / heterogeneous mixture). Next, I add some rose
petals and stir. I have made a(n) (element / compound / homogenous mixture / heterogeneous
mixture). I then allow the wax to cool and solidify. This is a (physical / chemical) change. The wax
solidifies at 30 C, which is an example of a (physical / chemical) property and a(n) (intensive /
, extensive) property. I light the candle and watch it react with oxygen. As the candle burns, I am
observing a (physical / chemical) change.
Answer:
Physical/homogenous mixture/heterogeneous mixture/physical/(physical /intensive/chemical
