A friend of yours went panning for gold last weekend and found a nugget
that appears to be gold. With your newfound scientific prowess, you set out
to determine if it is really gold. Your tests show that the nugget has a mass
of 7.6 g. Immersing the nugget in water raised the volume from 7.22 mL to
8.06 mL. The density of gold is 19.32 g/cm3. What will you tell your friend?

A certain half-reaction has a standard reduction potential E =-1.25 V. An engineer proposes using this half-reaction at the cathode of a galvanic cell that
must provide at least 0.80 V of electrical power. The cell will operate under standard conditions.

natural gas (CNG), natural gas that has been compressed into a much smaller
volume in the fuel tank. A newly designed CNG vehicle carries about several

carbon. If all of the natural gas is burned, how many kilograms of carbon dioxide will
be emitted into the atmosphere? Assume no residue remains and the carbon dioxide
is the only product in the combustion.

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc.
The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.
