Hydrogen sulfide is an impurity in natural gas that must be removed. One common removal method is called the Claus process, which relies on the reaction:

       8 H2S(g)  +    4 O2(g) ⟶  S8(l)  +  8 H2O(g)

a) If there were 30.00 g H2S and 50.00 g O2, what is the limiting reactant? (6 points)

b) What is the theoretical yield (S8) of the reaction? (2 pts)

c) How many grams of the excess reactant remain after the reaction? (4 pts)

d) What is the percent yield of the reaction if the actual yield is 27.5 g of S8? (3 pts)

 A Fajans titration of a 0.7908-gg sample required 45.32 mL of 0.1046 M AgNO₃. Express the results of this analysis in terms of the percentage of

a.      Cl^-

b.     BaCl₂·H₂O

Chemical structure

which tests would possibly work on your molecule. Lipitor chemical structure 

 why it tests positive, and what color /appearance the positive test result

would be. If a test is not applicable then leave it blank

       Test          Why positive/Color 

Solubility with water

Chromate test

lodoform test

Benedicts test

Fermentation test

lodine test

Seliwanoff's test

Biuret's test

Ninhydrin test

Xanthoproteic test
