How will fumes escape from The Crucible affect the weight of magnesium oxide?
Asked in Elements and Compounds
Why does magnesium gain weight when burned?
What happens when magnesium burns? What do you need for magnesium to burn? Will magnesium burn if you have it in a closed container? No. Why not? It needs air. Why does it need air? There is oxygen in the air. Magnesium needs oxygen to burn. So, when magnesium burns, you start with magnesium and end up with a compound that contains both magnesium and oxygen. Magnesium has an atomic weight of 24. Oxygen has an atomic weight of 16. So...

What is the purpose of taring the crucible before using it in an incineration process?
It reduces errors caused by variations in the weight of the crucible itself. Taring is accurately establishing the empty weight of the crucible, which can vary with contaminants, residue, or oxides. By repeatedly heating, cooling, and weighing the crucible, until there is only an acceptable variation between weighings, the actual weight of samples before and after incineration can be more precisely measured. ...
