Yes. You must be very careful with powdered magnesium as it is flammable and burns bright enough to damage your eyes.
Magnesium powder is elemental magnesium ground down to a fine powder.
you get magnesium oxide + iron
The magnesium powder is used as a source of illumination for the photo. Just for the older cameras, the ones we have today use lights not the magnesium powder.
For example the melting of this powder.
Yes it is. And you have not asked a question yet. The white powder is magnesium oxide.
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
the white powder is magnesium oxide. Magnesium burns in air with a dazzling white light to produce magnesium oxide. the equation is- 2Mg + O2 = 2MgO
magnesium look like white powder after burning in air. magnesium burns in air n react with atmospheric oxygen n forms magnesium oxide which is a white powder.
Magnesium nitride is formed when magnesium powder is burned in the presence of nitrogen gas.
The scientific name for baby powder is talcum powder, which is made from finely ground talc mineral.
magnesium oxide
I suppose that you think to magnesium chloride.
