Al(s)+3Ag+(aq) = Al3+(aq)+3Ag(s)SO3(g)+H2O(l) = H2SO4(aq)Ba(s)+Cl2(g) = BaCl2(s)Mg(s)+Br2(l) = MgBr2(s)

Concepts and reasonThe principle used to settle this trouble is based upon redox reactions.A oxidation reaction is a kind of reaction which entails transfer that electrons amongst two species. This reaction is additionally called oxidation-reduction reaction.

You are watching: Which of the following reactions are redox reactions? check all that apply.

FundamentalsIn oxidation process, there is rise in oxidation state of an atom, ion or molecule by shedding the electrons.In palliation process, over there is a diminish in oxidation state of one atom, ion or molecule by accepting the electrons.

Answer:

*
From this reaction, that is clear that there is no adjust in oxidation number of atoms.Due to this, this reaction is not a oxidation reaction.A redox reaction is a reaction in which there is a change of oxidation number of atoms current in reactant.

Write the well balanced chemical equation between aluminum and also aqueous systems of silver as follow.

*
From this reaction, that is clear the Aluminum undergoes oxidation and also silver experience reduction.Due to this, this reaction is redox reaction.

In this reaction, oxidation variety of Aluminum boosts from 0 come +1. So, aluminum undergoes oxidation. The oxidation number of silver decreases from +1 to 0. So, silver undergoes reduction.

Write balanced chemical equation as follow.

*
In this reaction, Ba experience oxidation and Cl experience reduction.This reaction is oxidation reaction.In this reaction, oxidation number of Ba boosts from 0 to +2 . So, Ba undergoes oxidation. The oxidation number of Cl decreases from 0 come -1. So, Cl experience reduction.

Write well balanced chemical equation together follow.
