For the reaction 2Co2S3 (s) + 9O2 (g) → 2Co2O3 (s) + 6SO2 (g). Given: O2 gas has a volume of 42.9 L, pressure of 905 torr, and temperature of 35 °C.
1) (4 points) What in the amount of O2 gas?
2) (4 points) What is the amount of Co2S3 (s) required to react with the given amount of O2 gas?

3) (4 points) What mass of Co2S3 (s) is required to react with the given amount of O2 gas

d

explanation:

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.
