Answer is: a bottle of acetic acid contains a solid.
Acetic or ethanoic acid (CH₃COOH) when undiluted is called glacial acetic acid.
Glacial acetic acid has freezing point (melting point) around 16.6°C, so it will be at solit state.
Vinegar is mixture of acetic acid (CH₃COOH) and water (H₂O). Vinegar is colourless liquid with sour taste and pungent smell, freezing point of the vinegar is lower than glacial acetic acid.
Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).
Balanced chemical reaction (dissociation):
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
Answer:
D) Low temperatures
Explanation:
Non-metals are elements that do not show metallic characteristics like heat conductivity, electrical conductivity, malleability, e.t.c. They are generally less dense and are bonded with weak forces in between their compounds.
The weakness of non-metals is the chief reason why they generally tend to have low boiling point. Only the presence of impurities can cause an elevation in their boiling points.
Metals on the other hand are good heat conductors and they generally have a high boiling point.
Answer:
B. 2 nitrogen, 4 hydrogen, and 3 oxygen
Answer:
The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A graduated cylinder large enough to hold both the object and enough water to fully immerse it is the best tool for this job.
