Solid copper reacts with solid sulfur to form solid copper I sulfide?
The chemical reaction between solid copper and solid sulfur results in the formation of solid copper (I) sulfide. This is a synthesis reaction in which copper and sulfur combine to form a new compound with a different chemical composition. The reaction is represented by the chemical equation: Cu + S -> Cu2S.
What distinguishes a compound like copper sulfide from an ordinary mixture of copper powder and sulfur?
Copper Sulfide is a wholly different chemical from copper and sulfur, and thus shows different characteristics and is not dividable by physical means, while a mixture of copper and sulfur powder is just a physical mix.
Is a Silverware tarnishing a physical or Chemical change?
It's a chemical change. The silver reacts with sulfur compounds from the air.
Is a yellow solid physical or chemical property of sulfur?
A yellow solid is a physical property of sulfur. It describes the appearance and state of the element at room temperature and pressure. Chemical properties, on the other hand, involve how sulfur reacts with other substances.
Is Using oxygen to separate molten copper sulfide into copper and sulfur dioxide a physical change?
No, using oxygen to separate molten copper sulfide into copper and sulfur dioxide is a chemical change because new substances with different chemical properties are formed. This process involves a chemical reaction where the copper sulfide is broken down into copper and sulfur dioxide molecules.
Solid copper reacts with solid sulfur to form solid copper you sulfide?
Copper and sulfur react to form copper(II) sulfide. This is a chemical reaction where copper atoms lose electrons and sulfur atoms gain electrons to form the compound. Copper(II) sulfide is a solid compound with a specific chemical structure.
Is using oxygen to separate molten copper sulfide into copper sulfur dioxide a physical change?
no it is a chemical change
What compound is formed with copper and sulfur?
Copper sulfide is the compound formed when copper reacts with sulfur. Depending on the ratio of copper to sulfur, different forms of copper sulfide can be formed, such as Cu2S and CuS.
Sulfur reacts with chlorine to form what compound?
Sulfur reacts with chlorine to form sulfur dichloride, which has the chemical formula SCl2.
What is the chemical equation for copper sulfatesulfur dioxideand water?
The chemical equation for when copper metal reacts with sulfuric acid to form copper(II)sulfate, sulfur dioxide gas, and water is Cu + 2 H2SO4 => CuSO4 + SO2 + 2 H2 O.
When heating sulfur what reaction physical or chemical?
When heating sulfur, a chemical reaction occurs. Sulfur undergoes a phase change from solid to liquid to gas as it is heated, but this is still considered a chemical change because the molecular structure of the sulfur is altered in the process.
Is copper sulfate a physical or chemical change when heated?
Thermal decomposition and loss of water are chemical changes.
