1. Using the equation and the value for k below, predict the direction using the following:
H2(g) +1218) 2HI(g)
K = 7.1 x 107 at 25°C
a. Q = 427
b. Q = 1522
c. [Hz]o = 0.81 M
[12]=0.44 M
[HI]o = 0.58 M
d. [Hz]o = 0.078 M
[12]o= 0.033 M
[HI]o = 1.35 M
e
[Hz]o = 0.034 M
[12]0= 0.035 M
[HI]o = 1.50 M

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende
