Solving appiled Mr. Auric Goldfinger, criminal mastermind, intends to smuggle several tons of gold across international borders by disguising it as lumps of iron ore. He commands his engineer minions to form the gold into little spheres with a diameter of exactly 6 cm and paint them black. However, his chief engineer points out that customs officials will surely notice the unusual weight of the "iron ore" if the balls are made of solid gold (density 19.3 g/cm"). He suggests forming the gold into hollow balls One of the balls of fake "iron ore," sliced in half. instead (see sketch at right), so that the fake "iron ore" has the same density as real iron ore (5.15 g/cm). Calculate the required thickness of the walls of each hollow lump of "iron ore." Be sure your answer has a unit symbol, if necessary, and rour digits.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

A recent snowstorm had the potential to create icy road conditions, which led to the closure of several roads in the area. One way ice on the road could be reduced is to apply a layer of NaCl. The expected rainfall for the area was approximately 6.0 inches, which would have created about 1.75 liters of standing water per square foot. How much NaCl, in grams, per square foot would have to be used to prevent ice formation if the temperature was only supposed to reach -2.5 C°? The kf of water is 1.86 1/C*mc and the density is 1 g/mL.

Most analytical machines used in science can either measure absorbance of light, like the spectrophotometers used BioZ 151 and 152 labs, or can measure change in electrical conductance. In order to convert things like absorbance values into concentration data, a linear regression is used. In order to determine nitrite concentration in water samples, nitrite is reacted with several chemicals to produce a purple color. The absorbance of the solution is measured from known amounts of nitrite to produce a standard curve to analyze samples. Use the data in the provided table, or from the linked spreadsheet to make a graph and perform a linear regression using treadline. mg/L NO3 Absorbance 0 0.1 0.3 0.5 0.7 o 0.183 0.542 0.914 1.298) 1.61) In order for this to work, samples must be diluted prior measurement so that the concentration falls within the range of the standard curve.
