Is it a physical or chemical change when iron rusts?
When iron rusts, it is a chemical change. The substance that is produced (the rust) is a completely new substance. Therefore, the iron has changed chemically, and not just physically, like being melted into a different shape. It's chemical structure has been altered.
Why are burning candle and rusting nails examples of chemical change?
Burning candles and the rusting of nails are examples of chemical changes owing to the fact that there are chemical reactions occurring and new chemical compounds are being formed as the reaction continues.When a candle burns, the wax and wick of the candle are undergoing combustion and (ideally) being chemically changed into carbon dioxide and water, which are two completely new chemical substances than were present in the candle. In the case of the nail, iron in the steel alloy from which the nail is made is combining with oxygen to form a chemical compound not present in the nail, namely iron oxide.
Is ductility a physical or a chemical change?
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
Is brewing a coffee chemical or physical change?
physical. the water being added simply soaks through the coffee, so there's no chemical change.
Is wheat being milled into flour a chemical change?
No. It is a physical change because the wheat's chemical composition does not change.
Why is rusting of a nail chemical change?
Its iron being converted into iron oxide (rust) by oxidation. That's chemistry.
Is rusting a physical change of metal?
Chemical Yes. The metal is being converted to an oxide of that metal. Most would (correctly) describe this as a chemical change, but physics has a lot to do with how that happens.
Why is butter a physical state and rusting a chemical change?
Butter is the physical state of being a solid, like a brick. Rusting is a physical change where the metal atoms of iron on the metal object combine with the atoms of another element, oxygen. This creates a new molecule, rust, or oxygenated iron.
What kind of change iron to rust?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
Is metal rusting a chemical change?
Firstly, only iron rusts. Other metals are said to corrode, but either is a chemical change.

What is an example of a phycisa rather than a chemical change acigarette being smoked sawdust that is piling up under a table an old garden rake that is rusting?
sawdust that is piling up under a table - is a physical change

Is a bicycle changes color as it rusts a chemical or a physical change?
It is a chemical change. Here oxidation of Iron occurs and being oxidation reaction, it is 'exothermic' reaction.Through it takes prolonged period and it is difficult to observe it, you can deduct it. As 'all' oxidation reactions are 'exothermic'.
Is ductility a physical or a chemical change?
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is milk being shaken into butter a physical change or a chemical change?
chemical change
