Trends in Hydrides and Reactions
1) BOILING POINTS OF THE GROUP 16 HYDRIDES
PERIOD OF PERIODIC TABLE HYDRIDE BOILING TEMPERATURE *C
2 H20 100
3 H2S -60
4 H2Se -41
5 H2Te -4
From the data above identify and explain any trends in the boiling temperatures of the group 16 hydrides, comment on the role played by inter molecular forces.
2) given an aqueous solution of copper ions (Cu2+ (aq)) what would you expect to happen when if you were to add the following metals into the solution:
a) zinc
b) gold
Also give your reasoning for any situation where you would expect a reaction to occur, discuss this in terms of transfer of electrons (equations are not needed for the answer)
