In 1909 Fritz Haber discovered the workable conditions under which nitrogen, N2(g), and hydrogen, H2(g), would combine to
produce ammonia. The conditions included medium temperature (-500°C), very high pressure (-351kPa), and an iron catalyst.
The reaction is represented by the equation:
N2(g) + 3H2(g) - 2NH3(g)

HOW MANY MOLES OF NITROGEN ARE NEEDED TO PRODUCE 1.20 miles of ammonia gas?

A. 0.60 mol N2

B. 1.21 mol N2

C. 1.67 mol N2

D. 2.40 mol N2

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.
