Pregunta 9
Pregunta
(In terms of oxygen) In the reaction between copper oxide and carbon, the copper oxide is [blank_start]reduced[blank_end] into copper and the carbon is [blank_start]oxidised[blank_end] into carbon dioxide. The copper oxide is the [blank_start]oxidising agent[blank_end] and the carbon is the [blank_start]reducing agent[blank_end]. It is a [blank_start]redox[blank_end] reaction.

Pregunta 10
Pregunta
(In terms of electrons) In the reaction between copper oxide and magnesium, the copper oxide is [blank_start]oxidised[blank_end] into copper and the magnesium is [blank_start]reduced[blank_end] into magnesium oxide. The copper oxide is the [blank_start]reducing agent[blank_end] and the magnesium is the [blank_start]oxidising agent[blank_end]. It is a [blank_start]redox[blank_end] reaction.
