What else can I help you with?
What oxidation number would you find on a metal ion and a non - metal ion?
A metal ion typically has a positive oxidation number equal to its charge, while a non-metal ion typically has a negative oxidation number equal to its charge. For example, a sodium ion (metal) has a +1 oxidation number, and a chloride ion (non-metal) has a -1 oxidation number.
if rotation did not occur, one side of the earth would be continutally exposed to the?
Sun
Does a nail rust in oil?
Nails can still rust in oil because oil does not prevent the exposure of the nail to air and moisture, which are the main causes of rusting. To prevent rusting, a nail would need to be completely sealed off from air and moisture.
Would an acid explode with metal?
An explosion doesn't occur.
Why must oxidation and reduction occur simultaneously?
Because for oxidation to take place the electrons lost by the substance that is oxidized must be accepted by atoms or ions of another substance. Also, for reduction to occur the electrons gained by the substance that is being reduced must be transferred from the atoms of ions of another substance. Therefore, oxidation and reduction are complementary processes: that is to say that oxidation cannot occur without reduction and visa versus.
What would you see if you were holding a metal that had luster?
If the metal had a metallic luster, on a freshly exposed, non-weathered surface, you would see a somewhat shiny, opaque surface.
Which redox reaction would most likely occur if silver and zinc metal were added to a solution that contained silver and zinc ions?
The most likely redox reaction would be the displacement reaction of silver ions by zinc metal, forming zinc ions and silver metal. This is because zinc is higher in the reactivity series than silver, so it has a greater tendency to lose electrons and undergo oxidation.
Does rusting of iron require the presence of oxygen and water for it to occur?
No. Only oxygen must be present. The process of rusting is the reaction of iron metal (Fe) combining with oxygen gas (O2) to form iron oxide (FeO or Fe2O3). Water (and salt) speed up this reaction a great deal, but oxygen is the only one that is necessary.
What Would happen if you had uranium in a enclosed container and exposed it to a large amount of electricity?
Being a metal Uranium would conduct electricity.
What is the oxidation number of b in nabh4?
+1 for Na, +3 for B and -1 for each H The IUPAC rules would have H as +1 except when bonded to a metal. Boron is a metalloid so it would have an oxidation number on that rule would be -5. It depends what rule you have been taught.
What is the Hydrogen oxidation number?
It largely depend on what H is bonded with. Usually, its +1, however, in the case of metal hydrides, it would be -1.
What is the reaction between a metal's surface and oxygen called?
When anything combines with oxygen, the process is called oxidation. When iron oxidizes, it forms rust. In other metals, oxidation as well as other chemical changes can be referred to as tarnish.
