Cu is being reduced and Zn is being oxidized, hence
Zn + CuSO4 --> ZnSO4 + Cu
An element that increases its oxidation number in a reaction has been oxidized. This means it loses electrons or gains a more positive oxidation state. You can determine which element is oxidized by comparing the oxidation numbers of the element in the reactants and products of the reaction.
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
If an element has gained electrons, it has been reduced. If an element has lost electrons, it has been oxidized. This can be determined by comparing the oxidation state of the element before and after the reaction.
Sodium (Na) is oxidized in the reaction to form sodium bromide (NaBr). In this reaction, sodium goes from an oxidation state of 0 to +1, indicating that it has lost an electron and been oxidized.
Al is oxidized because it loses electrons , O is reduced because it gains electrons.
An element that increases its oxidation number in a reaction has been oxidized. This means it loses electrons or gains a more positive oxidation state. You can determine which element is oxidized by comparing the oxidation numbers of the element in the reactants and products of the reaction.
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.
The material that is oxidized in the given reaction is Iron. Fe2O3 is iron oxide which can occur naturally as the mineral magnetite.
Bromine is the oxidizing element.
The element has lost one or more electrons in a reaction.
If an element has gained electrons, it has been reduced. If an element has lost electrons, it has been oxidized. This can be determined by comparing the oxidation state of the element before and after the reaction.
Sodium (Na) is oxidized in the reaction to form sodium bromide (NaBr). In this reaction, sodium goes from an oxidation state of 0 to +1, indicating that it has lost an electron and been oxidized.
Which element will be oxidized and which will be reduced
Al is oxidized because it loses electrons , O is reduced because it gains electrons.
Carbon
Phosphorus
In this reaction, Lithium is oxidized to Lithium ions (Li+) and Bromine is reduced to Bromide ions (Br-). Oxidation occurs when an element loses electrons (in this case, Lithium loses an electron), while reduction occurs when an element gains electrons (Bromine gains an electron).
