Hydrogen sulfide gas burns in oxygen to produce sulfur dioxide and water vapor.

what mass of oxygen gas is consumed in a reaction that produces 2 mol SO2?

96.0 grams of oxygen gas (O2) will be produced.

Option B is correct.

Explanation:

Step 1: Data given

Number of moles SO2 = 2.0 moles

Molar mass O2 = 32.0 g/mol

Step 2: The balanced equation

2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(g)

Step 3: Calculate moles oxygen gas (O2)

For 2 moles H2S we need 3 moles O2 to produce 2 moles SO2 and 2 moles H2O

For 2.0 moles SO2 produced we need 3/2 * 2.0 = 3.0 moles O2

Step 4: Calculate mass O2

Mass O2 = moles O2 * molar mass O2

Mass O2 = 3.0 moles * 32.0 g/mol

Mass O2 = 96.0 grams

96.0 grams of oxygen gas (O2) will be produced.

Option B is correct.

hi my dude or dudette

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.
