Rotting burning cooking and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds.
Rusting is a chemical change. Rust forms when iron or its alloys are exposed to moist air. The colour of the surface of the iron also changes in this reaction. When this acidic solution reaches iron two reactions occur.
A change in which one or more new substances are formed is known as chemical change. For example iron has the potential to rust given the right conditions. A change will not change the chemical make-up of the substance.
A new substance formed out of the reaction. For example burned wood becomes ash carbon dioxide and water. A chemical property describes the ability of a substance to undergo a specific chemical change.
The first statement is true while the second is false D. Technically its iron oxide hydrate because pure iron oxide isnt rust. Sublimation melting tearing and grinding are all changes.
The second statement is true while the first is false. Rust damages several things from cars bridges and ships to cooking utensils. Water can combine with carbon dioxide in the air to form carbonic acid a weak acid.
Hence rusting of iron is a chemical change. The rusting of iron is a chemical change because it is two substances reacting together to make a new substance. Rusting is undesirable and methods are used to avoid rusting.
