Based on the information given, classify cach of the pure substances as elements or compounds, or indicate that no such
classification is possible because of insufficient information,
Analysis with an elaborate instrument indicates that
• substance A contains two elements.
• substance B and substance C react to give a new substance D.
substance E decomposes upon heating to give substance F and substance G.
• heating substance H to 1000 *C causes no change.
• substance I cannot be broken down into simpler substances by chemical means.
substance I cannot be broken down into simpler substances by physical means.
heating substance K to 500*C causes it to change from a solid to a liquid.
