At some temperature and pressure, all of the above listed items except ice will be a liquid.
Calcium and Gold are metals and have no molecular structure. Neon is a Noble gas and is mono-atomic. Sodium chloride is ionic not molecular, even when liquefied.
Carbon dioxide is molecular but usually goes directly from a gas to a solid at one atmosphere of pressure. It would have to be very cold and pressurized to be a liquid.
The elements Hydrogen and Chlorine are diatomic, but would need to be very cold to become liquids at one atmosphere of pressure.
Vinegar is a solution of acetic acid molecules dissolved in water (which also has molecules). It is a liquid at room temperature.
Alcohol (ethanol) is a molecular liquid at room temperature and pressure.

Calcium and gold are metallic elements. Even when melted to the liquid state, there will only be atoms not molecules.
Neon is one of the noble gases. This means that the particles of neon gas exist in monoatomic form. Thus there will be no molecules of neon.
Sodium chloride in the liquid state will only have ions not molecules, since it is an ionic compound.
Carbon dioxide and hydrogen are gases at room temperature. After they become liquified when treated to extreme temperatures and pressures, they should have molecules.
Vinegar (ethanoic acid), chlorine (in liquid state) and alcohol (ethanol) all contains molecules.
Ice (as its name suggests) is a solid and therefore do not comply to the condition stated in the first place (unless in liquid form - water).

Alcohol and Vinegar! The first 3 are elements, sodium chloride is table salt, carbon dioxide is a gas we exhale, hydrogen is the lightest element, Chlorine is an element and a gas, and Ice is frozen water!

have you ever unquestionably examine the countless further information on right here? many circumstances the question became a lot greater advantageous without them. Then too, further information seem as you're answering or afterwards... there have been some circumstances that i've got neglected a factor of the small print or did no longer examine them.
