Consider the unbalanced reaction Ti(s) + Cl2(g) --> TiCl4(s) When 4.21 g of Ti react with 15.4 g of Cl2, 16.2 g of TiCl4 are obtained. The theoretical yield of TiCl4 is___, the limiting reactant is___and the percent yield is___ %. (Remember to use correct sig figs)

c is the answer because when something is left after something evaporates that shows the chemical change.

it takes on an electronical energy

the answer is d. 74.02

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.
