Old aspirin exposed to moisture often smells like acetic acid (vinegar). when aspirin is heated in boiling water, it decomposes and gives off a vinegar smell. the resulting solution gives a positive fecl3 test. why is this test positive? ( explain in detail! )

write the chemical equation for the reaction of aspirin and water at high temperature.

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.
