What happens when copper vessel is exposed to moist air for a long time give the chemical reaction that takes place?
When a copper vessel is exposed to moist air for a long time, it undergoes a chemical reaction with oxygen and moisture to form copper oxide (CuO) and eventually copper carbonate (CuCO3). Both of these are easily recognizable as a greenish layer of patina that forms on the surface of the copper.

What happens when copper is placed in acid?
When copper is placed in acid, a chemical reaction occurs where the copper reacts with the acid to form copper ions and hydrogen gas. This reaction results in the copper dissolving in the acid and producing a blue-green solution.
What happens during the reaction between copper and acid?
During the reaction between copper and acid, the copper metal reacts with the acid to form copper ions and hydrogen gas. This reaction is a chemical change where the copper metal is dissolved in the acid, releasing hydrogen gas as a byproduct.
What happens when iron is placed in copper sulfate solution?
When iron is placed in copper sulfate solution, a chemical reaction occurs where the iron displaces the copper in the solution, forming iron sulfate and copper metal. This is known as a displacement reaction.
What happens when copper reacts with alcohol?
When copper reacts with alcohol, it forms copper acetate and hydrogen gas. This reaction is a chemical process where the copper atoms combine with the alcohol molecules to create a new compound.
Is dissolution of a copper penny in nitric acid a chemical reaction?
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
What happens to copper's chemical property when it is exposed to air?
Copper, over the course of time, is gradually oxidized when exposed to air. It takes quite awhile for this reaction to occur naturally; however, the reaction is expedited with heat. The result is Copper oxide.
What is observed when copper sulphatepentahydrate is exposed to ammonia gas?
A chemical reaction is observed.
What happens to the atoms in copper oxide acid to call it a chemical reaction?
Copper and oxygen atoms form to create copper oxide. This is a synthesis reaction, and it can be created when copper is burned in a fire.
What happens when copper is placed in acid?

What happens when iron is placed in copper sulfate solution?
When iron is placed in copper sulfate solution, a chemical reaction occurs where the iron displaces the copper in the solution, forming iron sulfate and copper metal. This is known as a displacement reaction.
How can you tell that a chemical reaction occurred from the copper sulfate?
You can tell that a chemical reaction occurred with copper sulfate if there is a visible color change in the solution, such as the solution turning blue or green. Additionally, if there is a formation of a solid precipitate, like copper hydroxide forming as a blue-green solid at the bottom of the solution, it indicates a chemical reaction has taken place.
Can copper be broken down by chemical means?
Yes, if copper is exposed to wood, it decomposes rather quickly.
What happens when copper reacts with alcohol?
When copper reacts with alcohol, it forms copper acetate and hydrogen gas. This reaction is a chemical process where the copper atoms combine with the alcohol molecules to create a new compound.
Is dissolution of a copper penny in nitric acid a chemical reaction?
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
Is the reactivity of copper with oxygen considered a chemical or physical property?
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
What happens when hydrocloric acid is poured on a cu plate?
When hydrochloric acid is poured on a copper plate, a chemical reaction occurs. The acid reacts with the copper to produce copper chloride and hydrogen gas. This reaction can cause the copper plate to corrode or dissolve over time.
