Because magnesium oxide burns with an intensely bright white light and the dark glasses are to protect your eyes
Crystal glasses are not made out of crystal. They're made of regular glass in which the calcium is replaced with lead oxide or zinc, causing them to sparkle more than the usual type of glass.
As a matter of fact, there are two types of 'iron' : Ferrous(Fe2+) and Ferric(Fe3+)You should say either Ferric Oxide(Fe2O3) or Ferrous Oxide(FeO).Ferric Oxide balanced equation : 4Fe + 3O2 ===> 2Fe2O3Ferrous Oxide balanced equation : 2Fe + O2 ===> 2FeO
Magnesium Oxide
The ionic chemical formula of lead(IV) oxide is: (Pb)4+ + 2 O-.
Sodium oxide, Magnesium oxide, Copper oxide, Acidic oxide, Amphoteric oxide
Magnesium oxide is NOT an element.Corrected:It is an ionic compound made of two elements: Magnesium (note: correctly spelled here!) and Oxygen with formula: MgO
No, glass is a form of matter. Many, but not all, glasses are oxides.

Sodium oxide is a chemical compound with the formula Na2O. It is used in ceramics and glasses.- From the WikipediaYes Na2O does exist.
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.
The properties a glass is made up of depends on what type of glass it is. Some properties glasses contain are: silicon dioxide, sodium oxide, and sodium carbonate.

The formula for copper(II) oxide is CuO. This is the commonly met black powder. Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.

Lead has Three type of oxides: Lead(II) Oxide = PbO (Generally referred) Lead(IV) Oxide = PbO2 Lead(II,IV) Oxide = Pb3O4
