A scientist is examining an unknown solid. Which procedure would most likely help determine a chemical property of the substance?
heating it to find the temperature at which it melts
exposing it to a flame to see if it catches on fire
hitting it with a hammer to determine if it breaks or bends

Which statement best describes chemical properties of matter?
Chemical properties, such as density, must be observed when a substance is in its natural state at room temperature and normal atmospheric pressure.
Chemical properties, such as reactivity, must be observed when a substance is in its natural state at room temperature and normal atmospheric pressure.
Chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.
Chemical properties, such as boiling point, are generally observed as the identity of a substance changes and one or more new substances form.
