By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
Chemical, the resultant molecules have different structures and properties.
Can copper be broken down by chemical means?
Yes, if copper is exposed to wood, it decomposes rather quickly.
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.
What is the compound Cu20?
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.
The chemical reaction between copper oxide and carbon that produces copper and carbon dioxide is an example of?
decomposition

Chemical, the resultant molecules have different structures and properties.
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?
No. Copper oxide has no acid-base properties.
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?
HCL and copper oxide = Copper chloride+water
Reaction of copper and heat is physical change or chemical change?
If it is just heated, the reaction is physical. If there is burning in the process, than the state of the copper will change, making it a chemical reaction.
Write a word equation for copper oxide?
The chemical formula for copper oxide is CuO.
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.
