What is the volume, in milliliters, of 6.42 g of acetone? If you slice and slice a chunk of gold until only one tiny particle is left that cant be chopped any more without losing the properties that make gold gold, then youve got an atom. If there is one substance present and two phases present, does this describe a homogeneous mixture, a heterogeneous mixture, or a pure substance? If you slice and slice a chunk of gold until only one tiny particle is left that cant be chopped any more without losing the properties that make gold gold, then youve got an atom.\r\n

The atoms in an element all have the same number of protons. Back in the 1600s, this was a problem in the sugar cane plantations of the Caribbean, as they didn't have any real use for these molasses. And theyre represented in a strange table you may have seen at one time or another the periodic table.
