For each of the following experiments, decide whether a reaction will occur. If you think there will be no reaction. Write down why you think this. If you think a reaction will happen: write down why you think it will happen, what do you except to see and the word equation to go with it.
a] Iron heated with copper(II) oxide
b] aluminium heated with iron oxide
c] copper heated with iron oxide
d] magnesium heated with zinc oxide
Answers
Answer:
a) This Reaction Will Happen As Iron Is More Reactive Than Copper.
Iron+Copper Oxide-------->Iron(III) Oxide+Copper
b) This Reaction Will Happen As Aluminium Is More Reactive Than Iron.
Aluminium+Iron Oxide---------->Aluminium Oxide+Iron
c)This Reaction Will Not Occur As Copper Is Less Reactive Than Iron.
d) This Reaction Will Occur As Magnesium Is More Reactive Than Zinc.
Magnesium+Zinc Oxide---------->Magnesium Oxide+Zinc
Explanation:
Answer:
C] Copper heated with iron oxide -This reaction will not happen
Except it all three will occur.
Explanation:
a) This reaction will happen As iron is more reactive than Copper.
Iron+ Copper oxide →Iron (lll) Oxide + Copper
b) This reaction will happen As aluminium is more reactive than iron.
Aluminium + Iron Oxide Aluminium oxide +Iron
c)This reaction will not occur As a copper is less reactive than Iron so it will not displace iron from the oxide
copper+ iron oxide →no reaction
d) This reaction will occur as i magnesium is more reactive than zinc so can easily displace zinc from oxide
magnesium + Zinc Oxide. →+ Magnisium oxide+ zinc.
