If something is a physical property, it is possible to measure the property through observation that does not irreversibly changing the material that has the property. Chemical properties, on the other hand, are attributes of a substance that allow for a chemical change, often irreversible. They ...
A piece of copper is cut in half. Is this a physical change or a chemical change? Explain. Physical Change: A form of change occurs when the physical properties of a chemical substance or material change are generally referred to as physical change. Like, the dim...
What happens to the mass of copper when it is heated and forms copper (II) oxide? Describe tests used to identify unknown chemical Lithium Sulfide. Starting with copper metal, describe how a sample of crystals of copper (II) chloride may be prepared in t...
PURPOSE: To obtain an enzyme capable of catalyzing the oxidative reaction for producing an aldehyde, a carboxylic acid and a ketone from an alcohol and an aldehyde, especially producing 2-keto-L-gluconic acid (2-KGA) from L-sorbose through L-sorbosone.朝倉 明...

Dissolving metals is a chemical property that takes place when water or strong acids react with metallic objects. Chemical forces pull metal atoms from the object, causing it to break apart and leave the atoms floating freely in solution. Solubility depe
What is missing here ist the relation to physical/chemical status of that "copper". What are You talking about? Copper metal? Copper atoms as vapour? Copper ions I or II in aqueous solution? As a matter of fact, copper atoms are paramagnetic (one unpaired electron is enough despite the ...
