1.- Classify thefollowing redox reactions as combination, decomposition ordisplacement: a) P4 + 10Cl2 --->4PCl5,b) 2H2O2 ---> 2H2O +O2, c) Mg + 2AgNO3 --->Mg(NO3)2 + 2Ag, d)NH4NO2 ---> N2 +2H2O, e) 2NO --->N2 +O2,f) H2 + Br2 ----> 2HBr.
2.- Calculate the mass of KI in grams required to prepare 5.00x 102 mL of a 2.80 M solution.
3.- How would you prepare 60.0 mL of 0.200 M HNO3from a stock solution of 4.00 M HNO3?
