chemical change
The process of acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the chemical components of the paint, causing a permanent change in its chemical structure.
no, its physical change :)
Chemical broooooooooooooooo niga
No, dissolving a fizzy tablet like vitamin C in water is a physical change. The tablet is still vitamin C molecules, just dispersed in the water. Chemical bonds in the vitamin C molecules are not broken during the dissolving process.
No, this is a chemical property. When iron dissolves in hydrochloric acid, it undergoes a chemical reaction in which the iron atoms lose electrons and form iron(II) chloride, while hydrogen gas is evolved. This is a chemical change, not a physical change.

Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
Marble dissolving in acid rain is a chemical change. The acid reacts with the calcium carbonate in the marble to form new substances, such as carbon dioxide and water. This chemical reaction alters the composition of the marble, leading to its dissolution.
An acid is a chemical compound, not a physical or chemical change.

1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.

The chemical reactions of sulfuric acid are chemical changes.
It is a chemical change only if this acid react with the cloth.
