Question
When potassium permanganate is heated it produces potassium manganate, manganese dioxide and oxygen gas. This is an example of ______ reaction.
Answer: Option C
:
C
When potassium permanganateisheatedit produces potassium manganate, manganese dioxide, and oxygen gas. This means in the reaction heat is absorbed so it is an example of an endothermic reaction.
Exothermic reactions are those in which the heat is released.
Electrolysis is a process in which a substance undergoes decomposition by absorbing electrical energy.
Chemical reactions in which electrical energy is consumed are called electrochemical reactions.
