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.

Explanation:

Vinegar like smell is given off by aspirin when we tend to heat it in boiling water. The main cause of this vinegar like smell is due to the formation of acetic acid and a phenolic acid upon heating of aspirin.

As a result, it gives a positive test when treated with ferric chloride, that is, .

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
