Consider the balanced equation below.
kondaur [170]

The option which gives the correct mole ratios is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

<h3 /><h3>What is Mole ratio ?</h3>

It is a conversion factor between compounds in a chemical reaction, that is derived from the coefficients of the compounds in a balanced equation

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

The balanced equation for given reaction is as follows ;

2H₂S + 3O₂ --> 2SO₂ + 2H₂O

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 and they are as follows

  • H₂S - 2
  • O₂ - 3
  • SO₂ - 2
  • H₂O - 2

Therefore, correct option is H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2

Explanation:

  • An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  • Ion may be positively charged "cation" or negatively charged "anion".
  • Neutral molecule has a net charge of zero.

<em>So, the species that are ions are: </em>
