· The General Chemistry Demo Lab The Thermite Reaction [] [Introduction. Our demonstration of magnesium burning inside a block of carbon dioxide, is a terrific example of an exothermic (heat evolving) and thermodynamically favorable reaction.. Another great example of a thermodynamically spontaneous reaction is the thermite reaction.
· Having been in both general Chemistry and Organic Chemistry labs I can only tell you what I've used them for. The Iron Ring apparatus is usually used to suspend a watch glass or glass plate above an open fire to heat chemicals and allow reactions to proceed. You clamp the iron ring on a ring stand (it's got a long pole coming from a base) and place it well above where the bunsen burner ...
· An iron ring, sometimes referred to as an iron support ring, is used in chemistry labs to stabilize flasks mounted to a ring stand and support them over the work area. Some iron rings also include a clamp. During experiments, scientists have protocols they follow for safety. An iron ring provides support for flasks that may contain dangerous ...

Ring Clamps. Ring clamps connect to a ring stand. They come in several sizes and have a multitude of uses: holding a separatory funnel during an extraction, support for a heating mantle, or supporting a glass funnel in gravity filtration. You can add pieces of cut tygon tubing to the ring to serve as a cushion for separatory funnels. Often tape ...
Iron is the cheapest and one of the most abundant of all metals, comprising nearly % of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). The minerals taconite, limonite (FeO (OH)·nH 2 O) and siderite (FeCO 3) are other important sources.
