Part 1: Name the type of chemical reaction that occurs when aluminum (Al) 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.

Part 1: Name the type of chemical reaction that occurs when aluminum (Al) 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.

Explanation:

Part 1:

The chemical reaction in which a highly reactive metal displaces the less reactive metal from its compound, is called a chemical displacement reaction.

The order of reactivity of metals is  shown below:

K>Na>Ca>Mg>Al>Fe>Sn>Pb>[H]>Cu>Ag>Hg>Au>Pt

So, Al is more reactive than Cu and less reactive than potassium.

Part 2:

Al is more reactive than Cu and less reactive than potassium.

Hence, it does not react with KNO3 and reacts with Cu(NO3)2.

hope this !

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
