What is an example of a chemical change for iron?
rust is a chemical change for iron
What is the only evidence of a chemical change?
The only evidence of a chemical change is the formation of new substances with different chemical properties than the original substances. This can include changes in color, odor, temperature, or the formation of a precipitate.
What evidence indicates that a chemical change took place when the iron and sulfr combined to form iron sulfide?
When iron and sulfur combine to form iron sulfide, evidence of a chemical change includes the formation of a new substance with different properties than the reactants. This is indicated by the change in color, as the mixture transforms from the metallic gray of iron and the yellow of sulfur to the dark color of iron sulfide. Additionally, heat may be released during the reaction, and the new compound cannot be separated into its original elements by physical means, further confirming that a chemical change has occurred.
Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
What evidence indicates that a chemical change took place when the iron and sulfur combined to form iron sulfide?
Evidence of a chemical change between iron and sulfur to form iron sulfide includes color change (from grey to black), formation of a new substance with different properties, and the release of heat energy during the reaction. Additionally, chemical analysis showing the presence of iron and sulfur atoms in the product confirms a chemical transformation has taken place.
What would be an example of a chemical change that took a long time to occur?
The rusting of iron is an example of a chemical change that can take a long time to occur, depending on the environment. It involves the reaction of iron with oxygen and water over a period of time to form iron oxide (rust).
What is an example of a chemical change for iron?
rust is a chemical change for iron
Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
What evidence indicates that a chemical change took place when the iron and sulfur combined to from iron sulfur?
Evidence of a chemical change occurring when iron and sulfur combine to form iron sulfide includes the observation of color change from gray/brownish to black, the release of heat energy as the reaction occurs, and the formation of a new substance with different properties than the original iron and sulfur. Additionally, the mass of the iron sulfide formed would be equal to the combined masses of the iron and sulfur used in the reaction, as mass is conserved in chemical reactions.
What is the only evidence of a chemical change?
The only evidence of a chemical change is the formation of new substances with different chemical properties than the original substances. This can include changes in color, odor, temperature, or the formation of a precipitate.
Is getting iron from iron III oxide a chemical or physical change?
It is a chemical change.
Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Why iron sulfur are heated and form a non magnetic shiny grey substance is chemical change?
Heating iron and sulfur causes a chemical reaction to occur, resulting in the formation of iron sulfide, a new substance with different properties than the original elements. The change in color, from the original yellow of sulfur and silver-gray of iron, and the change in magnetic properties indicate a chemical change has taken place.
Is rusting of iron a physical or chemical change?
Rusting of iron is a chemical change. It occurs when iron reacts with oxygen and water in the presence of moisture, forming iron oxide (rust). This process involves a chemical reaction that changes the chemical composition of the iron.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
