Is Acid rain dissolving paint off a wall a chemical change or physical 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.
Is the dissolving of zinc in acid a physical or chemical change?
The dissolving of zinc in acid is a chemical change. This is because new substances are formed during the process, specifically zinc ions and hydrogen gas. It involves a chemical reaction between the zinc metal and the acid.
Is Cleaning a painted surface with acid a chemical or physical change?
Chemical broooooooooooooooo niga
Is dissolving steel into acid a chemical change?
no, its physical change :)
Is iron dissolving in hydrochloric acid with the evolution of hydrogen gas a physical property?
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.
Is Acid rain dissolving paint off a wall a chemical change or physical 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.
Is dissolving of sugar in concentrated acid a chemical of physical change?
Chemical change.
Is the dissolving of zinc in acid a physical or chemical change?
The dissolving of zinc in acid is a chemical change. This is because new substances are formed during the process, specifically zinc ions and hydrogen gas. It involves a chemical reaction between the zinc metal and the acid.
What change chemical or physical does acid rain dissolving paint off a wall fall under?
The dissolution of paint from a wall by acid rain is a chemical change. This occurs because the acidic components of the rain react with the chemicals in the paint, breaking down its molecular structure and altering its composition. As a result, the paint may lose its color and adhesion, demonstrating a permanent change in the material.
What is chemical change when dissolving?
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.

Is a dissolving zinc in acid a chemical change or 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
Is dissolving zinc in sulphuric acid is a chemical change?
Yes, the zinc reacts with th sulfuric acid to produce zinc sulfate and hydrogen gas.
Is dissolving steel into acid a chemical change?
no, its physical change :)
Is marble dissolves in acid rain physical or chemical change?
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.
Is dissolving an alka seltzer tablet a chemical change?
Yes, dissolving an Alka-Seltzer tablet is considered a chemical change because the tablet's ingredients (such as citric acid and baking soda) react when coming into contact with water to produce carbon dioxide gas, which results in the fizzing effect.
Is iron dissolving in hydrochloric acid with the evolution of hydrogen gas a physical property?
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.
