An unbalanced chemical equation is shown: 2NaNg → 2Na+ N2
Which of the following statements explains why the equation is not balanced? (4 points)

A) Four molecules of N2 should be produced during the decomposition.

B) Three molecules of N2 should be produced during the decomposition.

C) Four molecules of N2 should be produced during the synthesis reaction.

D) Three molecules of N2 should be produced during the synthesis reaction.

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.
