Salt dissolving in a glass of water, using electricity to break down water into hydrogen and oxygen, rust forming on an iron fence and gas burning on a stove.
Electrolysis and heat can separate a compound into its elements.
I hope this helped you!
Answer:
All are correct
Explanation:
This might be a little deceptive. The question shows H, O and N which would designate ELEMENTS.
However, all of these can also be considered compounds and molecules as well. BUT, they are H₂, O₂ and N₂ when they are molecules and compounds.
So it depends on the whether the question is being literal or not.
Answer:
118.75°C is the boiling point of a solution.
Explanation:
Mass of the solute that is barbiturates = 42.5 g
Molar mass of a solute = 184.2 g/mol
Moles of solute = 
Mass of the solvent that acetic acid = 825 g = 0.825 kg
Molality of the solution (m):
Elevation in boiling point is given as:
i = 1 (organic compound)
= Boiling temperature of solution.
T = boiling temperature of solvent that is acetic acid=117.9°C
118.75°C is the boiling point of a solution.
