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 acid rain dissolving paint off a wall a chemical change?
Yes, acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the molecules in the paint, causing a chemical reaction that breaks down the paint's structure and changes its composition.
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 dissolving a fizzy tablet like vitamin C in water a physical change?
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.
Is dissolving of sugar in concentrated acid a chemical of physical change?
Chemical change.

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 acid rain dissolving paint off a wall a chemical change?
Yes, acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the molecules in the paint, causing a chemical reaction that breaks down the paint's structure and changes its composition.
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 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.
