Textbook Question
Chapter 1.7, Problem 1.4CC
You are working in the office of a precious metals buyer. A miner brings you a nugget of metal that he claims is gold. You suspect that the metal is a form of “fool’s gold,” called marcasite, that is composed of iron and sulfur. In the back of your office, you have a chunk of pure gold. What simple experiments could you perform to determine whether the miner’s nugget is gold?

There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample.
You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change.
Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the
entire sample, and that the sample is in a sealed box, so that no matter can enter or leave.

If you did not know the identity of the metal in
your jar, what experiment might you have
done to prove that the metal was in fact the
element pure zinc?
Write two or three sentences describing what
property you would measure and how you
would measure it if you were in the laboratory.
We experimented on various elements: Mossy Zinc, Aluminum Turnings, Copper Turnings, Activated Carbon, and Iron Fillings. We identified the physical properties based on Color, Luster, Form, and Conductivity and the chemical properties based on reaction to HCl and CuCl2. We were tasked to identify if the given elements were metals or nonmetals. The result of our observation is shown in the image. Based on this, what elements are metals and nonmetals? Iron is known to be a metal however, the iron fillings did not conduct electricity and do not have a metallic luster. Does that mean they are not metal? Is it right to say "corroded" in the CuCl2, when the sample formed rust-like material on its surface?

- On October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forwardTwo general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different.
