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) I need around 100 words

Thanks

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, needs to be about 200-300 words.

There is an observable trend in the boiling points of the Group 16 hydrides. As the period of the element (other than hydrogen) increases, the boiling point decreases.
The Group 16 hydrides are polar molecules. The important types of intermolecular force of attraction (IMFA) that can be observed among the ...
