Predict if a reaction would occur when solutions of 0.1 M Al(NO3)3 and 0.1 M KI are combined. Explain your reasoning, and, if you predict a reaction will occur, include the net ionic equation for the reaction.

The reaction is impossible

Explanation:

Potassium is above aluminum in the electrochemical series hence it cannot be displaced by aluminum in a double decomposition reaction.

A double decomposition (often shown by a net ionic equation) is possible if and only if the reaction leads to the formation of an insoluble precipitate.

Such a reaction cannot occur here because the redox potential of potassium is far more negative than that of aluminum hence the reaction is impossible.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
