Question: Which describes a chemical property of copper? Select the correct answer below: O Copper is shiny (it reflects light). O Copper is reddish brown in color. Copper can be pulled into wires. O A brown gas is released when copper and nitric acid are mixed together.
When a chemical property is measured, the substance being observed is converted to a different substance or interacts with another substance. When water changes from solid to liquid, the H2O particles present in the solid form become H2O particles in the liquid form.
A physical property can be observed without a chemical reaction. When a chemical property is measured, the substance being observed is converted to a different substance or interacts with another substance. When water changes from solid to liquid, the H2O particles present in the solid form become H2O particles in the liquid form.
Electrical conductivity is a physical property. A copper wire is still copper while it is conducting electricity.
Copper metal is ductile. It can be ulled into thin wires. Copper does not react with water.
All samples of a pure substance have the same chemical and physical properties. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property).
Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat.
1 Answer. No new substances formed, but some some chemical bonds broken...... hmmmm. This is a physical change.
The main properties of copper are:High electrical conductivity.High ductility.Good heat conductivity.Corrosion resistance.Good machinability.Antimicrobial properties/biofouling resistance.Non-magnetic.
Heating copper hydroxide produces copper oxide, CuO, a black solid. Copper oxide dissolves in acid, regenerating the copper (II) ion, which once again binds to water. Finally, zinc metal reduces the hydrated copper (II) ion back to metallic copper while itself turning being oxidized to zinc (II) ions.
Copper can be formed and stretched into complex and intricate surfaces without breaking. This makes it possible to create spires, steeples, musical instruments, bowls, bed frames, tubes and a huge number of other useful and beautiful products.
Group 11Group 11, by modern IUPAC numbering, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au).
solidCopper is a chemical element with symbol Cu and atomic number 29. Classified as a transition metal, Copper is a solid at room temperature.
It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.
List three physical properties of copper. Answers could include reddish- yellow color, conductor of heat and electricity, malleable, melting point of 1084°C, and boiling point of 2562°C.
