What kind of reaction is MnO2 4 HCl to form MnCl2 2 H2O Cl2?

Redox reaction
Redox reaction: The addition of Hydrogen to a substance or gain of electron or oxygen called Reduction. The substance which gives Hydrogen for reduction or removes Oxygen is called a Reduction agent. Example: MnO2 + 4HCl → MnCl2 + 2H2O + Cl.

What is the balanced chemical equation of MnO2 HCl?

Mno2+Hcl=MnCl2+H2O+Cl2.

Is MnO2 4hcl MnCl2 Cl2 2h2o a redox reaction?

Assertion is true but Reason is false. Explanation: A redox reaction is a reaction which involves both oxidation and reduction simultaneously. In this given reaction the Cl(-) in HCl is oxidized to Cl2 while the Mn(+4) in MnO2 is reduced to Mn(2+) in MnCl2.

Is MnO2 4hcl a redox reaction?

Explanation: A redox reaction is a reaction which involves both oxidation and reduction simultaneously. In this given reaction the Cl(-) in HCl is oxidized to Cl2 while the Mn(+4) in MnO2 is reduced to Mn(2+) in MnCl2.

Which of the following statements about the given reaction are correct MnO2 HCl MnCl2 Cl2 H2O?

in the above chemical equation, MnO2 is getting reduced to MnCl2 as reduction is called as removal of oxygen. MnO2 is acting as Oxidizing agent for HCl to become H2O as oxidation is called as addition of oxygen. Hence the option c is correct.

Is MnO2 4HCl a redox reaction?

What occurs during the reaction below 4HCl MnO2?

the manganese is oxidized and its oxidation number changes from +4 to +2.
