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
I believe the answer is B, or option 2. It makes the most sense, and is a fact.
Alteration of the physical form of a drug outside its label is compounding
It is called compounding according to some sources.
Answer
MnO₄ + 2H⁺ +3NO₂⁻ →3NO₃⁻ + Mn²⁺ +H₂O
Explanation
This is a redox reaction (oxidation-reduction reaction) which involves the transfer of electrons between two species. i.e
Mn + 6e⁻→Mn²⁺ (reduction)
3N³⁺- 6e⁻→3Mn⁵⁺(oxidation)
