16. Study the Guidelines for Unit I you received on Day 1, we will not be doing entropy and
enthalpy until after this test. This test includes: homogeneous and heterogeneous,
intensive and extensive physical properties, physical vs chemical properties and changes,
Periodic table, periods, groups (Potassium is in which group and period), qualitative vs
quantitative, observation vs interpretation etc from the guidelines and Chapters 1 and 2.
This Test has:
a. 50 M.C. Questions
b. Test Quiz (1 page of handwritten question ) with element names and symbols, and
questions on sig.figs and sci. not. Matching from demos and activities in class. Calculations
with density and metric conversions
Key to some questions: 7. ANS: 1.05e-8 km; 8 ANS: 1; 9 ans. 4, 10. ans. 1; 11 ans. C;
13. ans D
