The diagram represents a convection current in the Earth's mantle. Descriptions of the events at each of the positions are shown. Move each number from the diagram to the blank box that describes the event
occurring at the position in the convection current.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
