A student starts with 23.0 grams of N2 gas and 32.0 grams of H2 gas. How many moles of NH3 will be produced? Determine the limiting reactant
N2 + 3 H2 → 2 NH3

"the periodic table is arranged in order of atomic number."

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.
