Diborane (B2H6) is widely used in the synrhesis of organic compounds. Diborane itself is made by the reaction 2NaBH4 +I2 -> B2H6 + 2NaI +H2. if 6,3 g of NaBH4 are rected with excess I2 how many grams of diborane could theretically e isolated? if 1.9 g of diborane is actually produced what is the percent yield of the reaction

you didnt put any of the following

50.23 i believe is correct but don't quote me on that.

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.
