Question

14. Fe2O3+ 2Al is an example of
1) Chemical combination
2) chemical displacement
3) Chemical decomposition
4) Chemical double displacement​

Answer 1

Answer:

This reaction is an example of a d) displacement reaction.

Here Aluminum is more reactive metal than Fe. Therefore Al will displace Fe from its oxide. This type of chemical reactions in which one of the element displace another is called as displacement reaction. Here less reactive metal is displaced by more reactive metal. Since one-time displacement is occurring, therefore, it is called as single displacement reaction.

Displacement reaction is applicable in both non-metals and metals.
