It could be either. Solid, liquid, and gas are different phases of matter and both compounds and elements are matter and can be in any of those phases depending on temperature and pressure.
A solid may be an element (iron), a compound (iron oxide), a mixture (iron ore).
A white crystalline solid can be either a compound or an element. It depends on the specific substance in question. For example, table salt (sodium chloride) is a white crystalline compound, while pure elemental sulfur can also be a white crystalline solid. Testing and analysis are usually needed to determine whether the solid is a compound or an element.
Sodium chloride (NaCl) is a compound, not a chemical element.
No. It is a compound - solid carbon dioxide.
No. Copper sulfate is a compound.
Lye is a compound. It is composed of sodium hydroxide (NaOH) when in its solid form.
It is a compound.
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
A solid can be either a compound or an element. A compound is a substance made of two or more elements chemically combined, like salt (sodium chloride). An element, on the other hand, is a substance made of only one type of atom, like iron or oxygen.
