By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
Is heating copper carbonate a chemical change?
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.
Can copper be broken down by chemical means?
Yes, if copper is exposed to wood, it decomposes rather quickly.
The chemical reaction between copper oxide and carbon that produces copper and carbon dioxide is an example of?
The chemical reaction between copper oxide and carbon that produces copper and carbon dioxide is an example of a reduction reaction. In this reaction, copper oxide gains electrons from carbon (which is oxidized) to form copper, leading to the reduction of copper oxide to copper.
What is the name of Cu2O?
CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
Is the statue of liberty color change is a physical or a chemical change?
chemical - due to copper contact with oxygen copper oxide
When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.
Is copper oxide an acid?
Copper oxide is not an acid. It is a basic compound because it can react with acids to form salts and water.
Is copper oxide a metal?
No, copper oxide is a compound and has some properties of a semiconductor.
What does iron oxide look like after iron has burned?
Because iron oxide is not iron and the chemical/physical properties of substances are different.
Is copper turing green a physical or chemical change?
It's a chemical change. Copper oxidizes to form copper oxide, which is similar to iron rusting. A color change very often indicates a chemical change.
What is the chemical equation for HCl and copper oxide?
The chemical equation for the reaction between hydrochloric acid (HCl) and copper oxide (CuO) is: CuO + 2HCl -> CuCl2 + H2O
Reaction of copper and heat is physical change or chemical change?
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
Write a word equation for copper oxide?
Copper oxide can be represented by the chemical formula CuO. The word equation for the reaction of copper oxide with hydrochloric acid is: copper oxide + hydrochloric acid → copper chloride + water.
Is nitrogen oxide a physical or chemical agent?
Is nitrogen oxide a chemical or physical agent
Can copper be broken down by chemical means?
Yes, if copper is exposed to wood, it decomposes rather quickly.
