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.
It depends on the composition of the rock, but the answer is "yes," abrasion can polish rock surfaces.
One effective way to polish copper is to mix equal parts of vinegar and salt to create a paste. Rub the paste onto the copper surface using a cloth or sponge, then rinse off with water and dry with a clean cloth. Alternatively, you can use a commercial copper polish following the manufacturer's instructions.
Ethyl acetate is commonly used as a solvent in paints, coatings, and inks. It is also used as a flavoring agent in food and as a solvent in the production of pharmaceuticals and perfumes. Additionally, ethyl acetate is used in nail polish removers and as a cleaning agent.
To maintain the shine of an obsidian rock, you can polish it using a soft cloth and a commercial jewelry polish. To reveal the colors within the obsidian, you can cut it using a lapidary saw or water-cooled tile saw. Be sure to wear appropriate safety gear when cutting the rock.
Ethyl acetate has two carbons in its main chain, while n-propyl acetate has three carbons. This leads to differences in their physical properties such as boiling point and solubility. Ethyl acetate is commonly used as a solvent in paints and nail polish remover, while n-propyl acetate is used in flavorings and fragrances.
Yes it is. Sources: I'm smart with science :P
Nail polish evaporation is a physical change. When nail polish dries, the solvent (usually a volatile liquid) evaporates, leaving behind the solid components that form the polish film. This process does not alter the chemical composition of the remaining substances but simply changes their state from liquid to gas.
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
The chemical compounds that make up the clear liquid kills your nail
It depends how you mean dull. Dull by wear or dull by oxidation? If it just becomes dull without being touched, then it is a chemical change. Metals readily react with non metals ie Oxygen. This will form a metal oxide layer on the exposed regions. This is why you need to sandpaper down some of the more reactive metals, when using them for conductivity experiments in school, as the oxide reduces conductivity.
because nail polish is soluble in spirit
Nail polish remover contains acetone which is a very good organic solvent. It dissolves the nail polish and helps to clean it off.
No. Everything that has mass and volume is a chemical or a part of a chemical. Chemical free shoe polish would have to be some form of energy.
It depends on the composition of the rock, but the answer is "yes," abrasion can polish rock surfaces.
There is a solvent that is marketed specifically for the purpose of removing nail polish, which is called nail polish remover. It works. Buy a bottle.
Nail polish is a chemical compound, a solvent as acetone for example.
because spirit absorbs the particals of nail polish and the surface of the nails look like pearl
