A copper wire (density \(=8.96 \mathrm{g} / \mathrm{cm}^{3} )\) has a diameter of 0.25 \(\mathrm{mm}\) . If a sample of this copper wire has a mass of 22 \(\mathrm{g}\) , how long is the wire?
The difference between a law and a theory is the difference between what and why. Explain.
Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 105.0 g and a volume of 10.12 mL, calculate the mass percent of copper in the piece of necklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. Refer to Table 1.5. Mass percent of copper $=\frac{\text { mass of copper }}{\text { total mass }} \times 100$
The properties of a mixture are typically averages of the properties of its components. The properties of a compound may differ dramatically from the properties of the elements that combine to produce the compound. For each process described below, state whether the material being discussed is most likely a mixture or a compound, and state whether the process is a chemical change or a physical change. a. An orange liquid is distilled, resulting in the collection of a yellow liquid and a red solid. b. A colorless, crystalline solid is decomposed, yielding a pale yellow-green gas and a soft, shiny metal. c. A cup of tea becomes sweeter as sugar is added to it.
Ethylene glycol is the main component in automobile antifreeze. To monitor the temperature of an auto cooling system, you intend to use a meter that reads from 0 to 100. You devise a new temperature scale based on the approximate melting and boiling points of a typical antifreeze solution $\left(-45^{\circ} \mathrm{C} \text { and }\right.\( \)115^{\circ} \mathrm{C} ) .$ You wish these points to correspond to \(0^{\circ} \mathrm{A}\) and \(100^{\circ} \mathrm{A},\) respectively. a. Derive an expression for converting between \(^{\circ} \mathrm{A}\) and \(^{\circ} \mathrm{C}\) . b. Derive an expression for converting between \(^{\circ} \mathrm{F}\) and \(^{\circ} \mathrm{A}\) . c. At what temperature would your thermometer and a Celsius thermometer give the same numerical reading? d. Your thermometer reads \(86^{\circ}\) A. What is the temperature in $^{\circ} \mathrm{C}\( and in \)\mathrm{FF}$ ? e. What is a temperature of \(45^{\circ} \mathrm{C}\) in 'A?
