a. A mug with DAD written to one side of the handle

b. A mug with MOM written to one side of the handle

c. A mug with DAD written opposite the handle

f. A remote control device

h. A screw

Step-by-step solution

The Chiral Objects

Chiral objects are those whose mirror images don’t superimpose on each other.

The objects whose mirror images superimpose on each other are called achiral.

Subpart (a) A mug with DAD written on one side of the handle.

A mug with DAD written on one side of the handle has a mirror image that does not superimpose each other. Therefore, it is chiral.

Subpart (b)

A mug with MOM written to one side of the handle has a mirror image that does not superimpose each other. Therefore, it is also chiral.

Subpart (c)

A mug with DAD written opposite the handle has a mirror image that does not superimpose on each other. Therefore, it is chiral.

Subpart (d)

A mug with MOM written opposite the handle has a mirror image that superimposes each other. Therefore, it is achiral.

Subpart (e)

A wheelbarrow has a mirror image that superimposes each other. Therefore, it is Achiral.

Subpart (f)

A remote-control device has a mirror image that does not superimpose on each other. Therefore, it is chiral.

Subpart (g)

A nail has a mirror image that superimposes each other. Therefore, it is Achiral.

Subpart (h)

A screw has a mirror image that does not superimpose each other.Therefore, it is chiral.
