1.	Which of the following statements about a compound is incorrect?A. A molecule of a compound has atoms of different elementsB. A compound cannot be separated into its constituent elements by physical methods of separationC. A compound retains the physical proepreties of its constituent elementsD. the ratio of atoms of different elements in a compound is fixed.
Answer» A compound is a pure substance containing two or more than two elements combined together in a fixed proportion by mass and which can be decomposed into its constituent elements by suitable chemical methods Further, the procperites of a compound are quite different from the properties of constituent elements e.g. water is a compound contianing hydrogen and oxygen combined together in a fixed proportionation. But the properties of water are completely different from its consituents, hydrogen and oxygen.
