Most metals react with acids to give off hydrogen. Only very nonreactive metals, like gold and platinum do not react with metals. An example would be:
Calcium + Hydrochloric Acid = Calcium chloride + Hydrogen gas
(Ca +2 HCl = CaCl2 + H2)
Metals react with oxygen because of a process called oxidation. When metals are exposed to oxygen in the air, the metal atoms lose electrons to the oxygen atoms, forming metal oxides. This reaction occurs because metals have a tendency to lose electrons and oxygen has a high affinity for gaining electrons. The formation of metal oxides is a type of chemical reaction that changes the properties of the metal and can lead to corrosion or rusting.
oxides are formed when a element reacts with Oxygen
of course not gallium does not react with oxygen you retards cuz if it did then something would happen if you would it in the air cuz oxygen is in the air
If Argon gas and Copper metal were mixed together, they would not react chemically because Argon is an inert gas and Copper is a stable metal. They would simply coexist without interacting with each other.
If you just let it in, It would be 99% of ordinary air. If you send a spark through it, it would be nitrogen dioxide (it is toxic).
You want something that reacts with water and is exothermic. An example would be an alkali metal (such as sodium), or perhaps oxygen salts that react with water
These substances are a combusible material and oxygen.
A compound containing a metal plus oxygen would be a metal oxide. For example: Sodium plus oxygen would produce Sodium oxide, Bismuth and Oxygen would produce Bismuth oxide, Zinc plus Oxyen would produce Zinc oxide and so on.
because it may have an adverse reation to the metal, for example and acid would react with the metal and disolve it!
no, water and water are the same thing. If you put it all together, you would still have water, nothing changed except for quantity.
Basic oxides
Yes. Potassium will react readily with oxygen to form potassium peroxide.
