No, that wouldn't be decomposition since it's not breaking down. It's actually an example of oxidation. If a nail is iron or Fe(s) then a rusty nail would be Fe2O3 (Iron Oxide). I believe the balanced formula would look like this... 4Fe(s) + 3O2 --> 2Fe2O3 If anybody sees any flaws in my logic, please feel free to correct. :)

Is removing nail polish chemical or physical change?

This is probably an example of the sort of ambiguity which is the reason 'physical' and 'chemical' changes tend not to be mentioned outside of early science education. The exact physical make-up of the solute (nail polish) is not changed, but chemical bonds are both broken and made in this process (various intermolecular bonds). The reaction is reversible, but then, all chemical reactions are reversible, but require extra energy put into the system to reduce the entropy. Probably the best approximation would be to say it is a physical change, since all/most of the molecules involved are structurally unchanged.


What is an equation for a rusty nail in hydrogen peroxide?

The equation for a rusty nail (iron) reacting with hydrogen peroxide is: Fe(s) + H2O2(aq) -> Fe(OH)2(s) The iron in the nail reacts with hydrogen peroxide to form iron(II) hydroxide as a precipitate, which appears as the rust.


Why does not an iron nail rust in calcium chloride?

Calcium chloride is a drying agent that absorbs moisture from its surroundings, preventing the iron nail from being exposed to water, which is needed for the rusting process to occur. In the absence of water, the iron nail is unable to undergo the chemical reaction that leads to rust formation.


What happens when you put an iron nail into blue copper sulphate?

iron(Fe) being more reactive than Copper(Cu) displaces Cu from copper sulphate (CuSO4). Thus, the following equation is derived:Fe + CuSO4 -----> FeSO4 + CuOBSERVATIONS-1. reddish-brown deposit on the surface of nail2. surface of the nail is found corroded3. the blue solution turns light green


What happens when iron nail is added to zinc sulphate solution?

When an iron nail is added to zinc sulfate solution, a displacement reaction occurs where iron displaces zinc from the solution. This results in the formation of iron sulfate solution and zinc metal deposited on the iron nail. The reaction can be represented as: Fe(s) + ZnSO4(aq) -> FeSO4(aq) + Zn(s).

Will nails go rusty if touched by a rusty nail?

no, rust is not a disease, rust is a chemical reaction that occurs when iron reacts with water and air


Is a rusty nail physical or a chemical change?

The rusting of a nail is a chemical change. This is because the iron in the nail reacts with oxygen in the air to form iron oxide, which is the rust. This process involves a chemical reaction and results in a change in the composition of the nail.


What will happen to a rusty nail when its put into coke or other substance?

When a rusty nail is put into coke or another acidic substance, the rust (iron oxide) will undergo a chemical reaction with the acid to form soluble iron compounds. This process will dissolve the rust and remove it from the nail, leaving behind clean iron.


Is a rusty nail chemical weathering?

Rusting is oxidation, a chemical reaction.


Is a rusty nail a chemical or physical change?

Well, honey, a rusty nail is a chemical change. When that nail starts rusting, it's a whole chemical reaction going on between the iron in the nail and the oxygen in the air. So yeah, it's not just a little physical makeover, it's a full-blown chemical transformation.

Are rusty nails physical or chemical?

rusting of nails is a chemical reaction. iron combines with oxygen to form iron oxide which is rust. water/water vapour acts as a catalysthere.


How is a rusting a nail a chemical change?

Rust is a chemical reaction called oxide. When a nail rust, the chemical change is related to the reaction of the metal and oxygen.


Is rusty an adverb?

Rusty is not an adverb (a word that modifies a verb, adjective, or other adverb). Rusty is an adjective (a word that describes a noun). Example: rusty nail.
