and from urban environments in Atlanta and New York City. Most surprising, said the researchers, were the variations they saw in samples taken from the same sites. In most cases, up to 70% of the compounds at a site were distinct from each other in consecutive samples. ...
substances are combined, but there's nochemical reactionor bonding like that found in compounds. The individual substances in a mixture retain their ownpropertiesand can be separated into their original components. Air, saltwater and liquid dish soap are examples of mixtures. ...
