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.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
