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⁻

Option (3) southern states threatened to secede from the Union over the issue of slavery
Explanation:
By the 18th century, the United States faced a number of issues. For example, the slave trade was one of the issues that resulted in the state being brought into turmoil. This was because the United States was already divided into two - the Northern region and the Southern region. The Northern region was the one region that still held to slave trade despite it being abolished. The South, offered slaves freedom. Thus, the movement of he slaves from the North to the South was a major issue. Thus, the war was over the trade as the north though it was suffering due to the decrease in slave labor.
2, 4, 1
Explanation:
We have the following chemical reaction:
Ag₂O → Ag + O₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
2 Ag₂O → 4 Ag + O₂
