Write the net chemical equation for the production of manganese from manganese (ii) carbonate, oxygen and aluminum

Explanation:

..(1)

Manganese (II) carbonate and oxygen reacts to give manganses (III) oxide with carbon-dioxide gas.

..(2)

Manganese (III) oxide  reacts with aluminum metal to give aluminum oxide and manganese metal

On adding (1) and 2(2)  we will get the net net chemical equation for the production of manganese. So,

The net balanced equation we got:

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.
