Answer:
1. benzoic acid
2. p-cresol
3. Aniline
Explanation:
<u>1. Dissolving the mixture in a water-immiscible organic solvent - NaHCO₃, H₂O, CH₂Cl₂:</u>
Only benzoic acid will react with the base, sodium bicarbonate and will form ionic salt which is soluble in the water and thus benzoic acid acids gets separated in the aqueous medium.
<u>2. Dissolving the mixture in a water-immiscible organic solvent - NaOH, H₂O, CH₂Cl₂:</u>
p-cresol will react with strong base NaOH and form a salt with sodium ions which is soluble in water and thus p-cresol gets separated in the aqueous medium.
<u>3. Dissolving the mixture in a water-immiscible organic solvent - H₃O⁺Cl⁻, H₂O, CH₂Cl₂:</u>
Aniline will react with H₃O⁺Cl⁻ and form salt, anilinium chloride which is soluble in water and thus aniline gets separated in the aqueous medium.
Toulene will remain in the organic layer.
Answer:
b
Explanation:
the baloon is made to hold more air.
Both sides need to be balanced?
Molarity = moles of solute/volume of solution in liters.
From this relation, we can figure out the number of moles of solute by multiplying the molarity of the solution by the volume in liters.
We have 53.1 mL, or 0.0531 L, of a 12.5 M, or 12.5 mol/L, solution. Multiplying 12.5 mol/L by 0.0531 L, we obtain 0.664 moles. So, in this volume of solution, there are 0.664 moles of solute (HCl).
Answer:Energy is coverted into a waterfall
Explanation:Answer:A waterfall is a sudden drop in a river as it flows over a rock cliff. This happens when the river passes from a layer of hard rock to a layer of softer rock, and the water erodes away the softer rock. A watershed is the term given to the land that drains water into a particular stream, lake, or river.
