2H2S + 3O2 2SO2 + 2H2O Which option gives the correct mole ratios? H2S:SO2 = 2:2 and O2:H2O = 3:2 H2S:SO2 = 2:3 and O2:H2O = 3:2
UkoKoshka [18]

<u>Correct Answer:</u><u> Option (A) </u>

H₂S : SO₂ = 2:2 and,

O₂: H₂O = 3:2

Explanation:

The mole ratio is the ratio of coefficients of the compounds involved in the reaction. <u>R</u><u><em>eactants,</em></u><u> as on the left hand side of the chemical reaction which reach to for</u>m new products.

In the given reaction,

2H₂S + 3O₂ ⇒ 2SO₂ + 2H₂O

<u>The reactants are :</u> H₂S (hydrogen sulphide) & O₂ (oxygen)

<u>The products are :</u> SO₂ (sulphur dioxide) & H₂O (water)

  1. 2 moles of hydrogen sulphide react with 3 moles of oxygen
  2. 2 moles of sulphur dioxide & 2 moles of water are produced

Therefore correct option is

H₂S : SO₂ = 2:2 and,

O₂: H₂O = 3:2

3. Describe how the water at the equator would be different from the<br> water at the poles.
Dmitry_Shevchenko [17]

Answer:

there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.
