Get started for freeYou are presented with a block made of some pure metal and told the metal is gold, but you have your doubts. Using a thermometer, how can you determine whether the metal is gold?
Match each symbol with the correct element name: (a) Na (b) Fe (c) Co (d) Sn (e) \(\mathrm{Mn}\) Possible names: neon, fermium, copper, mercury, cobalt, scandium, magnesium, phosphorus, manganese, iron, sodium, potassium, argon, tin, silver, gold, calcium.
Which one of the following is an elemental substance: water, \(\mathrm{H}_{2} \mathrm{O} ;\) bronze, made by melting copper and tin together; table salt, \(\mathrm{NaCl}\); ozone, \(\mathrm{O}_{3} ;\) sulfur dioxide, \(\mathrm{SO}_{2} ?\)
When exposed to oxygen in the air, white phosphorus, \(\mathrm{P}_{4}\), catches fire and produces the compound \(\mathrm{P}_{4} \mathrm{O}_{10}\). Is this a description of a physical property or a chemical property of phosphorus? Explain.
