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

a) Test tube 1 will have a more vigorous reaction than test tube 2.
b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.
c)
i.- Sulfuric acid because is a strong acid
ii.- Acetic acid because is a weak acid.
Answer:
I think it's the last one
D. The cell is prokaryotic because it does not have any membrane-bound organelles.
Explanation:
The difference between eukaryotic and prokaryotic cells are that the eukaryotic cells have a nucleus and they have membrane-bound organelles, and prokaryotic cells don't.

Answer:
Kₐ = 5.7 x 10⁻⁵
Explanation:
The equilbrium for this acid is
HC₃H₃CO₂ + H2O ⇄ H₃O⁺ + C₃H₃CO₂ ⁻ ,
and the equilibrium constant for acrylic acid is given by the expression:
Kₐ = [ H₃O⁺][ C₃H₃CO₂⁻ ] / [ HC₃H₃CO₂ ]
Since the pH of the 0.23 M solution is known , we can calculate [ H₃O⁺].
The ][ C₃H₃CO₂⁻ ] is equal to [ H₃O⁺] from the above equilibria (1:1)
Finally [ HC₃H₃CO₂ ] is known.
pH = - log [ H₃O⁺]
taking antilog to both sides of the equation
10^-pH = [ H₃O⁺]
Substituting
10^-2.44 = [ H₃O⁺] = 3.6 x 10⁻³
[ C₃H₃CO₂⁻ ] = 3.6 x 10⁻³
Kₐ = ( 3.6 x 10⁻³ ) /0 .23 = 5.7 x 10⁻⁵
Explanation:
Factory wastes are usually acidic and they pose serious environmental challenges.
If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.
On land, the acid can enter into the soil and prevent plant growth.
Acid discharge can enter the groundwater system and render it unfit for use.
Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.
