What else can I help you with?
What does iron oxide look like after iron has burned?
Because iron oxide is not iron and the chemical/physical properties of substances are different.
What evidence of chemical change occur in iron rust?
The evidence of chemical reaction in the rusting of an iron nail is a color change. This is due to the formation of iron oxide, which is the reaction between iron and oxygen.
What are the two properties of iron oxide that are different from iron?
Density and melting point are different.
Is the color of iron wire a physical or chemical change?
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
Is iron rusts a physical or a chemical change?
Rusting of iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This reaction leads to the formation of a new substance with different properties from the original iron.
What does iron oxide look like after iron has burned?
Because iron oxide is not iron and the chemical/physical properties of substances are different.
Is iron oxide an acidic or basic or neutral oxide?
Iron oxide is considered a neutral oxide because it does not have acidic or basic properties. It is a compound that is formed by the reaction of iron and oxygen.
What evidence of chemical change occur in iron rust?
The evidence of chemical reaction in the rusting of an iron nail is a color change. This is due to the formation of iron oxide, which is the reaction between iron and oxygen.
Does iron oxide contain any nickel?
No. By definition iron oxide is a compound of iron and oxygen.
What are the two properties of iron oxide that are different from iron?
Density and melting point are different.
Is the color of iron wire a physical or chemical change?
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
is iron rusts a chemical or physical change?
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
If Iron and oxygen form rust is it a chemical or physical reaction?
The formation of rust from iron and oxygen is a chemical reaction. This is because the iron reacts with oxygen in the air to form a new compound, iron oxide (rust), which has different chemical properties from the original iron.
Can you use a magnet to separate iron oxide into iron and oxygen?
No, because Iron oxide is not a mixture of Iron and Oxygen. It is a compound in which iron and Oxygen have been chemically combined to create a new substance, which has different chemical and physical properties form either of the two elements which it is made from.
Fe2O3 is named iron oxide because it contains which type of iron ions?
Fe2O3 is named iron oxide because it contains Fe+ ions.
What is the formula for iron three oxide?
Fe2O3 ---------
Is car rusting physical change?
No, a car rusting is a chemical change because a new substance is formed. Iron will react with oxygen (found in water) forming iron oxide. The product, iron oxide, has different properties from both iron and oxygen. A "chemical change" describes any reaction where a new substance is formed. However, if a substance just changes forms, it is a physical change. For example, water freezing is a physical change.
