(2 points) Well, we might as well try a similar question. Magnesium metal reacts with hydrochloric acid to produce hydrogen gas and an aqueous solution of magnesium (II) chloride. What substance is being oxidize

In the given chemical equation, the substance getting oxidized is magnesium metal.

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

The chemical equation for the reaction of magnesium and hydrochloric acid follows:

The half reaction for the above equation follows:

Oxidation half reaction:

Reduction half reaction:

Hence, in the given chemical equation, the substance getting oxidized is magnesium metal.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
