What oxidation number would you find on a metal ion and a non - metal ion?
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.
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.
if rotation did not occur, one side of the earth would be continutally exposed to the?
Sun
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.
Would an acid explode with metal?
An explosion doesn't occur.
What happened to the exposed end of the spoon after five minutes?
After five minutes, the exposed end of the spoon likely experienced changes due to environmental factors such as temperature and moisture. If the spoon was metal, it might have become warm or even hot if left in contact with a heat source. If it was in a humid environment, condensation could have formed, leading to potential oxidation or tarnishing. Overall, the exposed end would show signs of interaction with its surroundings.
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.
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.
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 to a set of metal tools left outdoors in the rain for a long time?
If a set of metal tools is left outdoors in the rain for an extended period, they would likely develop rust due to the oxidation of iron in the metal when exposed to moisture and oxygen. The rust would weaken the structural integrity of the tools, making them less effective and potentially unusable. Additionally, prolonged exposure to moisture could lead to other forms of corrosion, depending on the type of metal and any protective coatings present. Regular maintenance and proper storage are essential to prevent such damage.
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.
