Magnesium is able to copper, and copper is able to magnesium.

zinc is able to magnesium, and magnesium is able to zinc.

copper is able to zinc, and zinc is able to copper.

in every blank, the options are "oxidize" and "reduce"

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Oxidizing agents:

Oxidizing agents oxidize the other elements and itself gets reduced.

Reducing agents:

Reducing agents reduced the other element are it self gets oxidized.

In given example,

Magnesium is able to reduced the copper and copper is able to oxidized the magnesium.

Zinc is able to oxidized the magnesium and magnesium is able to reduced the zinc.

Copper is able to oxidized the zinc and zinc is able to reduced the copper.

they both have a y in them
