separation techniques are used. A mixture is made up of elements and/or compounds that have not been chemically combined together. By separating the constituents of mixtures, we can learn about the properties of known/unknown substances in mixtures and potentially use them to make useful substances...

Miller used energy sources and the mixtures that were supposed to be found in the world at that time. In addition to ultraviolet rays, Miller accepted lightning, that is, electrical discharge, occurring as a result of atmospheric movements as a source of energy. In addition ...
They won’t let you bring it on the plane… but many have packed it frozen in the check-in bags. Your clothing will insulate it like a cooler and keep it frozen during the travel. I would but it in a plastic bag, twist and fold over… ...
