Question

1.    Identify the oxidizing and reducing agent and determine in the following reactions. Which reactant gets oxidized? Which reactant gets reduced?

Pb + PbO2 + 2H+ + 2HSO4-    --->   2PbSO4 + 2H2O

2.    Use the EMF series to determine if the following reactions will occur

   a) Fe + SnCl2 --->   FeCl2 +Sn

   b) 2Au + 2HCl --->   AuCl + H2

Ideal Gases

3.    Calculate the volume of HCl formed in L if 1L of hydrogen(g) reacts with 1L of chlorine(g) if this reaction were conducted at STP (T = 298.15K and P = 1atm)

                                                         H2(g) + Cl2(g) ---> 2HCl(g)

4.    What would be the volume of HCl formed if we incorrectly believed that hydrogen(g) was composed of only 1 atom of hydrogen and chlorine(g) was composed of only one atom of chlorine?

                                                         H(g) + Cl(g) ---> HCl(g)

Please give me the solution, Thanks.
