Answer: Theoretical mass of sodium sulphate ( 
) is 514.118 grams.
Explanation: For a given reaction,
As NaOH is used in excess, therefore it is an excess reagent and 
is a limiting reagent as the quantity of the product will depend on it.
We are given 355 grams of .
Molar mass of = 98.079 g/mol
Molar mass of = 142.04 g/mol
1 mole of is producing 1 mole of , so
98.079 g/mol of will produce 142.04 g/mol of
355 grams of will produce = 
of
Mass of = 514.118 grams
Answer:
C₁₂H₂₂O₁₁ and CH₃OH
Explanation:
Sucrose and methyl alcohol are nonelectrolytes. They do not ionize or conduct a current in aqueous solution.
HC₂H₃O₂ is a weak electrolyte. It produces only a few ions and is a poor conductor of electricity in aqueous solution.
HC₂H₃O₂ + H₂O ⇌ H₃O⁺ + C₂H₃O₂⁻
H₂SO₄ is a strong electrolyte. Its first ionization is complete, so it is a good conductor of electricity in aqueous solution.
H₂SO₄ + H₂O ⟶ H₃O⁺ + HSO₄⁻
