Answer:
Mount Everest is the highest point on Earth, and Death Valley is relatively flat.
Explanation:
Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert. It is one of the hottest places on Earth, along with deserts in the Middle East and the Sahara, Mount Everest is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point.
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).
Natural gas is primarily composed of methane (CH4)
Natural gas is a naturally occurring hydrocarbon mixture which is primarily composed of Methane(CH4), but it also contains ethane,propane and heavier hydrocarbon. In addition it contain small amount of nitrogen, carbon dioxide,hydrogen sulfide and traces amount of water.
It could be source for the battery, switch or interrupter for the lever, charge for the bulb and conductor for the wire.
If you do not this, I suggest brushing up on delocalization as well as sigma/pi bonds. Benzene is the only one of the 5 with any pi bonds, so this should be a relatively easy question if you are familiar with the concepts. I would search up a detailed (not to detailed though) explanation of both.
