1. In the previous lab (“Exploring Equilibrium”) you investigated the effect of temperature on equilibrium position; you may have found that temperature did not affect equilibrium in quite the way you expected. Add 80 A’s and 80 BC’s to the box for the first reaction and begin the experiment; let the reactions run until equilibrium is reached. Knowing Le Châtelier’s Prinicple, now predict and explain what will happen to the equilibrium position when the temperature is raised and lowered. Then test your ideas using the sim and explain your observations. Give numerical data to support your claims.

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.
