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)

Why do metals react with oxygen?
When metals react with oxygen they produce metal oxides. A common example would be that of Iron which in the presence of oxygen and water form rust (a mixture of metal oxides and metal hydroxides)
What two substances would react together in a combustion?
These substances are a combusible material and oxygen.
What element reacts with a metal or a non-metal to form an oxide?
oxides are formed when a element reacts with Oxygen
Does gallium react 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
How will the different properties of metals affect the way that sculptors use them?
After knowing the different properties of metals sculptors can be careful about which metal to use in which environment. If they didn't know the preporties the the metal would react with oxygen which would tarnish the metal or corrode it which would waste metal or make it look less beautiful.
What chemicals can heat water when added to it?
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
What elements would you react together to make the compound iron sulphide?
it says sulphide so it is oxygen so it is iron, sulphur and oxygen but not in this order you may need to research the order as it is a certain one
Why Gold is used instead of calcium to make jewelry?
Gold is a very inert metal. It does not readily react with water or the air(oxygen). Calcium on the other hand is a very reactive metal . If jewellery was made from it , it would react with the skin, air, and water.
Compounds composing of metal 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.
Why would an unknown chemical not be put into a metal container?
because it may have an adverse reation to the metal, for example and acid would react with the metal and disolve it!
Would potassium bond with oxygen?
Yes. Potassium will react readily with oxygen to form potassium peroxide.
What would be the result when alkali metals react with oxygen?
Basic oxides
