1. What mass of solid Lanthanum (III) oxalate nonahydrate { La2 ( C2O4 )3 ∙ 9 H2O } can be obtained from 650 mL of 0.0170 M aqueous solution of LaCl3 by adding a stoichiometric amount of sodium oxalate ?
2. Calculate the mass of hydrogen formed when 25 grams of aluminum reacts withexcess hydrochloric acid.
2Al + 6HCl → Al2Cl6 + 3H2
3. What mass of ZnCl2 can be prepared from the reaction of 3.27 grams of zinc with3.30 grams of HCl?
Zn +2HCl → ZnCl2 + H2
4. How many milliliters of 0.200 M NH2OH are needed to react with 12.0 mL of 0.550 M FeCl3?
FeCl3 + 3NH4OH Fe(OH)3 + 3NH4Cl
