Inorganic Chemistry
Hydrogen, iodine, and hydrogen iodide gases have reached equilibrium in a container at 700K. Equilibrium partial pressures are 0.28 atm HI, 0.033 atm H2, and 0.045 atm I2. For H2 (g) + I2 (g) --> 2HI, K=53. Half the HI is removed form the container and equilibrium is reestablished. Calculate the new partial pressure (in atm) of HI in the new equilibrium mixture.

THE REACTIONS OF METAL WITH ACIDS LAB: Aluminium (powder), manganese, lead, iron, zinc, copper and tin are reacted with both hydrochloric acid and sulphuric acid (H2SO4) and then used a wooden splint to light the inside of the test tube reaction.
1a) Was a gas produced in each case?
b) List the metals for which a gas was produced
c) Identify the gas produced, when the flaming splint test was positive.
2) What is the source of gas??
3) Write a balanced chemical equations for all of the reactions in which metal was observed to react.
4) Compare the reactions involving hydrochloric acid with those involving sulphuric acid.
5) Rank( calcium, sodium, potassium, and the 8 from this lab) plus hydrogen in order of decreasing reactivity! ....hint, activity series
6) Suggest a possible explanation why some metals react vigorously with acid or water while other metals do not appear to react at all.

Inorganic Chemistry
A silver nitrate solution was standardized by dissolving 0.54 grams of NaCl into 120 ml of solution using 4.0 drops of 1.0M K2CrO4 for an indicator (1ml=20 drops). Upon titrating with 43.6 ml of AgNO3, the Ag2CrO4 just began to precipitate. At this point in the titration the system reaches equilibrium and therefore Qsp for silver chromate is equal to Ksp of silver chromate and Qsp for silver chloride is equal to Ksp for AgCl.
A.) calculate the equilibrium concentration of chromate ion.
B.) calculate the equilibrium concentration of the silver ion
C.) calculate the equilibrium concentration of the chloride ion
D.) calculate the percent Cl- remaining in solution
E.) calculate the molarity of the AgNO3 solution used
