Question

Consider the balanced equation below.

2H2S + 302 → 2802 + 2H20
Which option gives the correct mole ratios?
H2S: SO2 = 22 and Oz: H20 = 3:2
H2S: SO2 = 2:3 and Oz: H20 = 3:2
H2S:502 = 4 4 and Oz: H20 = 5:4
HES:S02 = 4.6 and 02:H20 = 4: 4

Answer 1

a) H2S:SO2 = 2:2 and O2:H2O = 3:2

Step-by-step explanation:

• 2H2S + 3O2 → 2SO2 + 2H2O

⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2

⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2
