Answer 1

yes all the displACEMENT REACTIONS ARE  redox reactions.

there are two types of redox reaction

1. metal displacement reactions 2. non metal displacement reaction

1. metal displacement reactions- these r reactions in which 1 metal is displaced by another metal element and these rxns are useful in metallurgy that needs some strong reducing agents and thus all metal displacement reactions are redox reactions

2. non metal displacement reactions - these are basically based on h and o displacement and as for just an example we see that a gp 1 or gp. 2 element easily on reaction give out h2 molecule and thus converting its oxidation state from -1 to 0 as in metal hydrides oxidation state of h is -1 instead of +1 thus it also proofs to be a redox reaction thus proved that all displacement reactions are redox reaction
