Magnesium
that is magnesium itself, in the form of a ribbon
In chemistry, "en" refers to ethylenediamine, a compound commonly used as a ligand in coordination complexes. It is significant because it can form stable complexes with metal ions, influencing their reactivity and properties.
ribbon
This is the analytical chemistry.
Non-metal oxides are compounds that contain a non-metal element bonded with oxygen. They tend to be acidic in nature and can react with water to form acids. Non-metal oxides play a role in atmospheric chemistry and can contribute to acid rain when they dissolve in water droplets.
A medal bar or medal clasp is a thin metal bar attached to the ribbon of a military decoration or any other medal. So it is the type of military decoration which shows achievement of a campaign or operation.
what form is metal sold
When metal atoms replace hydrogen atoms in an acid, it forms a salt and hydrogen gas. The metal reacts with the acid to form the salt, while hydrogen gas evolves as a byproduct. This is a common reaction in chemistry known as a displacement reaction.
Sheet metal thickness can be determined by measuring it. Several specialty tools are available to tell how thing the sheet metal is in actual measurement or by guage, a form of measurement that is used for various types of sheet metal thickness.
If you are close to a university library you could consult the Handbook of Chemistry and Physics, if it's still available in printed form.
This was alchemy.
A metal and a non-metal tend to form a salt.
