Using examples, explain the difference between a physical property and a chemical property.
Ammonia gas is used as a refngerant in large-scale cooling systems. The density of ammonia gas under certain conditions is \(0.625 \mathrm{~g} / \mathrm{L}\). Calculate its density in \(g / \mathrm{cm}^{3}\)
Chlorine is used to disinfect swimming pools. The accepted concentration for this purpose is 1 ppm chlorine, or \(1 \mathrm{~g}\) of chlorine per million grams of water. Calculate the volume of a chlorine solution (in milliliters) a homeowner should add to her swimming pool if the solution contains 6.0 percent chlorine by mass and there are \(2.0 \times 10^{4}\) gallons of water in the pool. ( 1 gallon \(=3.79 \mathrm{~L} ;\) density of liquids $=1.0 \mathrm{~g} / \mathrm{mL} .
How many minutes does it take light from the sun to reach Earth? (The distance from the sun to Earth is 93 million \(\mathrm{mi} ;\) the speed of light \(=3.00 \times 10^{8} \mathrm{~m} / \mathrm{s}\).)
