a sample of carbon dioxide from a burning piece of charcoal contains 27% carbon and 73% oxygen. A different sample of carbon dioxide also contains 27% carbon and 73% oxygen. The percentages are the same for all samples analyzed. Explain these observations with respect to atomic theory.
Water (H2O) methyl alcohol (CH3OH ethyl alcohol (CH3CH2OH), ethylene glycol (HOCH2CH2OH), and sucrose (C12H22O11) are commonly classified as
