    C. with gases, the volumes consumed and produced are in ratios of small whole numbers.

    Elements are made of extremely small particles called atoms.
    Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.
    Atoms cannot be subdivided, created, or destroyed.
    Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
    In chemical reactions, atoms are combined, separated, or rearranged.
