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⁻
Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>
I hope it helps!

Certain fish species use bioluminescence as a form of "night light". Some use it for communication. Certain species of crustaceans send out coded signals to others of their own kind during mating season. Other creatures use bioluminescence as a trap.
<span>The right answer here is that the best explanation for why the rusting of an iron nail in the presence of water and oxygen is an oxidation-reduction reaction is answer B) electrons are transferred. This is the only answer that actually explains the chemical reasoning behind the reaction.</span>
