Caffeine is a solid at room temperature.
Temperature or pressure.
Liquid state because boiling point is 216Celsius , Melting point is -10degree Celsius
Copper nitrate is a chemical compound and not a state like a U.S. state. It is a solid compound at room temperature.
Barium chloride is a compound, not a state. It is typically found as a white crystalline solid at room temperature.
A mood ring is a ring which contains a thermochromic element, such as liquid crystal. The ring changes color in response to the body temperature of its wearer. The color is said, by some proponents, to indicate the emothional state of the wearer.
Molecular compounds can exist in various states at room temperature, including gases (e.g. oxygen and nitrogen), liquids (e.g. water and ethanol), and solids (e.g. sugar and salt). The state of a molecular compound at room temperature depends on factors such as the intermolecular forces present and the molecular structure.
An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state . A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard ambient temperature and pressure (SATP), whereas a molecular compound can be in a solid, gas or liquid state at SATP.
Covalent compounds at room temperature are typically in the solid or liquid state. Some covalent compounds may also exist as gases at room temperature, depending on their molecular weight and intermolecular forces.
A compound that is likely not a gas at room temperature would be a larger molecule with higher molecular weight, such as a long-chain hydrocarbon or a complex organic molecule. These molecules have stronger intermolecular forces holding them together, making them more likely to be in a liquid or solid state at room temperature.
Since Oxygen exists in combined state in nature, it is termed as a molecular element and Sucrose is a molecule of Carbon, Hydrogen and Oxygen with no charge on it, hence it is considered a molecular compound.
Temperature or pressure.
The molecular formula for chromous hydroxide is Cr(OH)2. In this compound, chromium has a +2 oxidation state and forms a compound with hydroxide ions.
I am sure it is in a solid state.
Liquid state because boiling point is 216Celsius , Melting point is -10degree Celsius
