A mixture of gases containing 26.0 g SO2, 4.0 g H2, and 20.2 g Ne at 23°C is in a 5.00-L container. What is the partial pressure of H2? (10pts)

Write the name for Sn(SO4)2. (Remember that Sn forms several ions.)

Although it is poisonous, the cyanide anion is actually used in chemical reactions, including the synthesis of some drugs. You can make a cyanide anion by doing a Bronsted acid/base reaction with hydrogen cyanide. Such a reaction is shown below, where the hydrogen cyanide is Bronsted acid and the dihydrogen phosphate anion is the Bronsted base to form phosphoric acid and the cyanide anion.. Based on the provided pKa values, is this reaction favorable, can you use a dihydrogen phosphate anion  to convert hydrogen cyanide into a cyanide anion?

Calculate the molarity of a 2L solution containing 180g of glucose.  (Hint:  The molecular weight of glucose is 180g/mol).  Be sure to show your work for full credit.

  After a rainstorm the pH of the water in an outdoor swimming pool is found to have dropped to 5.0. What is the concentration of the hydronium ions, H3O+,  in the swimming pool? pH = -log10 [H3O+] Kw  = 1 × 10-14

Determine the limiting reactant (LR) and the mass (in g) of H2O that can be formed from 15.0 g C8H18 and 45.0 g O2. (10) (Molar masses: C8H18 = 114 g/mol, O2 = 32 g/mol, CO2 = 44 g/mol.)  2 C8H18 + 25 O2 → 16 CO2 + 18 H2O
