In acetic acid, CH3COOH, the OH hydrogen is more acidic than the CH3hydrogens. Explain.
Chemistry Vocabulary Chapter One Mixture: physical combination of two or more pure substances. There is no fixed ratio for the included substances. The substances can be physically taken apart. Solid: do not conform to their container, highly organized. Liquids: takes the shape of its container, moves a lot more. Gases: molecules move freely, they fill the whole container. Pure Substance: has a fixed composition that has not been changed Compounds: made up of atoms of two or more different elements. There is a fixed composition of atoms and molecules (ex. Amount of oxygen in H2O), and they must be chemically taken apart. Atoms: the smallest unit of an element that can exist as a stable, independent entity. You will never be able to see an atom. Elements: made up of atoms of one type. Molecule: fixed number of atoms (at least two) held together by chemical bonds in a certain spatial arrangement. * All compounds are molecules, but not all molecules are compounds. Molecules can have just one element, ex. H2. AND molecules can also be compounds.
