- You are given a hammer, a battery, a bulb, wires and switch.(a) How could you use them to distinguish between samples of metals and non- metals?(b) Asses the usefulness of these tests in distinguishing between metals and non-metals?7. State whether each of the following represents a chemical change or merely a physical change:(a) A few grams of sucrose (table sugar) are placed in a small beaker of deionized water; the sugar crystals “disappear,” and the liquid in the beaker remains clear and colorless.(b) A copper statue, over time, turns green.(c) When a teaspoon of baking soda (sodium bicarbonate) is placed into a few ounces of vinegar (acetic acid), volumes of bubbles (effervescence) are produced.Classify each property as physical or chemical. (a) the tendency of copper to turn green when exposed to air(b) the tendency of automobile paint to dull over time(c) the tendency of gasoline to evaporate quickly when spilled(d) the low mass (for a given volume) of aluminum relative to other metals
- The radius of an atom of krypton (Kr) is about 1.9 Å. (a) Express this distance in nanometers (nm). nm Express this distance in picometers (pm). pm (b) How many krypton (Kr) atoms would have to be lined up to span 1.0 mm? atoms (c) If the atom is assumed to be a sphere, what is the volume in cm³ of a single krypton (Kr) atom? cm³Chemistry (b) A sampling plan is necessary to ensure that a laboratory sample is truly a representative of the entire population.
