In a famous experiment, Stanley Miller provided evidence for the theory of evolution. He placed CH4, NH3, H2, and H2O in a glass sphere and excited the gases using electricity and UV light. If the partial pressures of the gases were 340 mm Hg, 125 mm Hg, 65 mm Hg, and 100 mm Hg, what was the total pressure in the glass sphere?

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.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
