Boiling an egg is definitely a chemical change because a boiled egg can't be changed back to a raw egg.The process which can't be changed back to the original form are called chemical change.So,it is definitely a chemical change. Source(s): IX standard physics book. Gowtham Â· 9 years ago.
The substances that undergo chemical change in the reaction (1.1), magnesium and oxygen, are the reactants. The new substance, magnesium oxide, formed during the reaction, is the product. A word-equation shows change of reactants to products through an arrow placed between them.uring this reaction (1.29), the copper(II) oxide is losing oxygen and is being reduced. The hydrogen is gaining oxygen and is being oxidised. In other words, one reactant gets oxidised while the other gets reduced during a reaction. Such reactions are called oxidation-reduction reactions or redox reactions.
