Consider the balanced equation below.

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
h2s: so2 = 4: 4 and o2: h2o = 5: 4
h2s: so2 = 4: 6 and o2: h2o = 4: 4

the balanced equation is as follows

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation

molar ratio can be determined by the coefficients of the compounds in the balanced reaction

coefficient is the number in front of the chemical compound

coefficients for the compounds in this reaction are as follows

H₂S - 2

O₂ - 3

SO₂ - 2

H₂O - 2

therefore correct option is

H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

can you list the answers so i can answer
