Answer:
Iron is oxidized while chlorine is reduced.
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.
Consider the following reaction:
2FeCl₂ + Cl₂ → 2FeCl₃
in this reaction the oxidation state of iron is increased from +2 to +3. That's why iron get oxidized and it is reducing agent because it reduced the chlorine. The chlorine is reduced from -2 to -3 and it is oxidizing agent because it oxidized the iron.
2Fe⁺²Cl₂⁻²
2Fe⁺³Cl₃⁻³
The iron atom gives it three electrons to three atoms of chlorine and gain positive charge while chlorine atom accept the electron and form anion.
Answer:
C. glaciers
Explanation:
Glaciers are a part of the hydrosphere
The hydrosphere is the amount of water on the earth. It includes water in the different states found on the earth surface and within the subsurface. Water does exists as solids, liquids and in vapor form on earth.
- Glacier is the solid form of water on the earth crust.
- It is a significant part of the hydrosphere.
- Most glaciers are found around the polar regions and high altitude zones on the earth.
- It is an important source of fresh water for the ecosystem
