Part 1: Name the type of chemical reaction that occurs when aluminum (AI) reacts with copper nitrate (Cu(NO3)2). Part 2: Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate. (10 points)

single replacement reaction

This reaction is called a single replacement reaction. This is because aluminum is more reactive than copper so replaces copper to form aluminum nitrate.

This is because aluminum is more reactive than copper so replaces copper to form aluminum nitrate. Therefore, as aluminum is less reactive than potassium it will not replace potassium to form aluminum nitrate but will replace copper as it is more reactive than copper.

Explanation:

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
