wow i haven't blogged in few weeks! sorry! anyways, today we did this lab with magnesium oxide and it was pretty cool because we got to see real sparks fly and gas being burned and all that cool stuff. We had carefully measured out a specific amount of magnesium and put it into the bottom of a crucible. then we lit a flame and turned on the gas and cooked it until the magnesium oxidized. The way to check was to lift the lid of the crucible and if there was smoke coming out or the magnesium was brightly lit then that meant it wasn't done cooking. It was cool to see how bright the magnesium got just being exposed to the air for a few seconds. I think that was just the best part: seeing the reaction of the magnesium and the oxygen was cool enough :)

ReplyDeleteHi,
ReplyDeleteMagnesium oxide is a white solid mineral that occurs naturally as periclase and is a source of magnesium. It also is used as a dietary supplement when the amount of magnesium in the diet is not enough. Thanks a lot...
