Which set of properties would identify an unknown white solid as a molecular compound?
To identify an unknown white solid as a molecular compound, one could examine its physical properties such as low melting and boiling points compared to ionic compounds, which typically have higher values. Additionally, molecular compounds are usually poor conductors of electricity in solid and liquid states, as they do not contain free-moving ions. Solubility in nonpolar solvents would also suggest a molecular nature, as many molecular compounds are more soluble in organic solvents than in water.

How can the properties of matter identify an unknown substance?
The properties of matter, such as physical characteristics (melting point, boiling point, density, solubility) and chemical properties (reactivity, pH, combustion), can help identify an unknown substance by providing a unique profile. By comparing these measured properties to known standards or databases, one can match the unknown substance to a specific compound. Additionally, techniques like spectroscopy and chromatography can further refine identification by revealing molecular structures and compositions. Overall, a systematic analysis of both physical and chemical properties allows for accurate identification of unknown substances.

The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
