  1. 1.

    A student investigates a silver-gray solid sample in a laboratory to determine its fundamental characteristics. The sample has a density of 2.70 g/cm³, melts at 660 °C, conducts electricity in the solid state, and vigorously releases bubbles of hydrogen gas when placed into dilute hydrochloric acid. Based on these observations, which statement correctly classifies the observed characteristics into physical and chemical properties?

    • A) Density and the reaction with hydrochloric acid are chemical properties, whereas melting point and electrical conductivity are physical properties.
    • B) Density, melting point, and electrical conductivity are physical properties, whereas the reaction with hydrochloric acid is a chemical property.
    • C) Electrical conductivity and the reaction with hydrochloric acid are chemical properties, whereas density and melting point are physical properties.
    • D) Density, melting point, and the reaction with hydrochloric acid are chemical properties, whereas electrical conductivity is a physical property.
