Answer from: aduncan3426

The rigid parts of acetylsalicylic acid are $\boxed{{\text{ring structure}}}$ and $\boxed{{\text{C = O}}}$ .

Further explanation:

$\pi$ bonds are the bonds formed by the sideways overlap of two p orbitals. Rotation essentially means that parallel orientation would have to be destroyed. Thus the breaking of such bonds requires a considerable amount of energy hence they do not rotate freely.

Acetylsalicylic acid is commonly referred as aspirin. Its IUPAC name is ${\text{2 - acetylbenzoic acid}}$ .

In terms of rigidity, the bonds that are easily rotated without any restriction of breakage of bonds are not regarded as rigid while the bonds that do not rotate due to restricted rotation due to pi-electron cloud are not so rigid.

In acetyl-salicylic acid, there are two kinds of ${\mathbf{\pi }}$ bonds namely the carbon-carbon within the aromatic ring and carbon-oxygen bond. Hence these are the only two rigid $\pi$ bonds that can only be rotated if they are broken. The carbon-oxygen $\pi$ bond and the carbon-carbon bond in the ring are evident in the image attached.

Therefore the rigid parts of acetylsalicylic acid include ring structure and ${\mathbf{C = O}}$ .

Answer from: Quest

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.
