Magnesium Lab

In my chemistry class, we performed a lab to see how much magnesium weighs(both burnt and in metal form), as well as how conductive it is. We used the following materials: crucible, ribbon of magnesium, scale, and a gas torch. We weighed the crucible by itself, it came to 11.61g. We also weighed the crucible and magnesium together before putting it under the gas torch, that turned out to be 12.01g. By subtracting both of those weights, we found that the magnesium ribbon piece(without heat) we used was approximately .60g. We put the crucible with the magnesium inside over the gas torch. It took a while for the crucible to get hot enough for the magnesium to start to burn, but when it did, the magnesium burned incredibly bright, it was almost blinding. The magnesium burned to an ash; at this point, we weighed both the crucible and the ash together, that came to 12.17g. Subtracting the crucible alone from that weight, the ash itself only weighs .56g. Out of all of this, we learned how magnesium behaves under heat. Below is a picture of how bright magnesium actually gets under heat.
