All of the examples given are examples of a chemical change. Methane contains carbon and hydrogen but no oxygen.
ththe rusting of iron in a humid atmosphere
decomposition of water into hydrogen and oxygen gases
decomposition of water into hydrogen and oxygen gases
I thought those two are also chemical?
What part of ALL did you not understand? All four examples you listed are examples of a chemical change. The question, as stated, has no correct answer listed.
