∙ 14y agoBoiling hydrogen sulfide is a physical change, as it is a reversible process where the substance changes from a liquid to a gas due to the absorption of thermal energy. The chemical composition of hydrogen sulfide remains the same during boiling.
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
The chemical equation Mg + H2S -> MgS + H2.
Yes, silver tarnishing is considered a chemical change. It occurs when the silver reacts with sulfur compounds in the air or on the surface, creating silver sulfide, which gives the silver a darker appearance. This chemical reaction alters the composition of the silver, making it different from its original state.
Tarnish of silver is a chemical change. It occurs when the silver reacts with sulfur compounds in the air to form silver sulfide, creating a darkened appearance on the surface of the silver.
The chemical formula for potassium hydrogen sulfide is KHS.
The chemical formula for hydrogen sulfide is H2S.
The chemical formula for hydrogen sulfide is H2S.
The tarnishing of silver when it comes in contact with hydrogen sulfide in the air is a chemical property. This is because a chemical reaction occurs between the silver and the hydrogen sulfide, leading to the formation of a new compound on the surface of the silver.
The chemical formula for hydrogen sulfide is H2S.
The chemical formula for the hydrogen sulfide ion is (HS^-).
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
The chemical formula for two hydrogen atoms and one sulfur atom is H2S, which represents hydrogen sulfide gas.
The chemical equation for the reaction between sulfur and hydrogen is: S + H2 → H2S. This reaction forms hydrogen sulfide gas.
The chemical formula for hydrogen sulfide is H2S.
The chemical symbol for hydrogen sulfide is H2S.
The chemical equation Mg + H2S -> MgS + H2.
The chemical formula for calcium hydrogen sulfide is Ca(HS)2. This compound is formed when the metal calcium reacts with hydrogen sulfide gas.
