Ammonium nitrate can be made to decompose spontaneously according to 5NH4NO3(s) → 4N2(g) + 9H2O(g) + 2HNO3(g).

If 400. kg of NH4NO3(s) are detonated in a volume of 2000. L at a temperature of 1727 °C, find the total pressure of the products after the reaction goes to completion.

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.
