What is elemental magnesium?
Magnesium powder is elemental magnesium ground down to a fine powder.
When you heat iron oxide powder with magnesium powder?
you get magnesium oxide + iron
What is the physical change of magnesium powder?
For example the melting of this powder.
What is the name of the white powder that is left when you burn magnesium?
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
What is the name of the powder when magnesium has burnt?
the epsom salt of magnisium is used as theTalcum powder.

How is magnesium used in photography?
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.

When the magnesium burns in air a white powder is formed?
Yes it is. And you have not asked a question yet. The white powder is magnesium oxide.
What happens when bleaching powder reacts with dil sulphuric acid?
RTYU
When you heat copper oxide and magnesium why do you get grey powder?
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.
What is the name of the white powder that is left when you burn magnesium?
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
What does magnesium look like after burning in air?
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.
How is magnesium sulphate made?
"A strong electrolyte dissociates completely into ions in aqueous solution. When magnesium sulfite, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.MgSO3(s) Mg2+(aq) + SO32-(aq)"*This is a quote from OWL, the chemistry homework site.Basically, if you don't feel like reading above, magnesium sulfite dissociates completely and makes Mg2+ and SO32- pretty cool huh?
How does nitrogen gas react with magnesium?
Magnesium nitride is formed when magnesium powder is burned in the presence of nitrogen gas.
What is that mysterious white powder?
magnesium oxide
