Part 1. a chemist reacted 18.0 liters of f2 gas with naci in the laboratory to form ci2 gas naf. use the ideal gas law equation to determine the mass of naci that reacted with f2 at 290. k and 1.5 atm.
f2 + 2 naci > ci2 + 2naf
part 2. explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at stp.

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
