Provided here is a reversible reaction that is exothermic. Which of the following correctly describes the result of a change in temperature to this chemical system? N2 + 3H2 ⇔ 2NH3 + heat * A decrease in temperature would result in more nitrogen being produced.
An increase in temperature would result in less ammonia being produced.
A decrease in temperature would result in less ammonia being produced.
An increase in temperature would result in less hydrogen being produced

gravity causes stares to cluster i think so

more infor would

a lot

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.
