Students are preforming a lab experiment in chemistry class where they must find out what 3 mystery solutions are. The bottles are not labeled,
but one of the bottles contains NaCl, another bottle contains AgNO3, and
another bottle contains K2SO4. The students decide to mix one drop of
each unknown chemical with one drop of some known chemicals to see if
precipitates form in order to identify the unknown chemicals. Use the data
table below to determine each unknown. *

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal. b. he is determining chemical properties that are sufficient to identify the metal. c. he is determining physical properties that are insufficient to identify the metal. d. he is determining chemical properties that are insufficient to identify the metal.
