• A)you will need 23.6 g Cl₂ for complete reaction and will produce 66.7 g of AlCl_3.
• B)you will need 53.2 g Cl₂ for complete reaction and will produce 66.7 g of AlCl_3.
• C)you will need 26.6 g Cl₂ for complete reaction and will produce 49.0 g of AlCl_3.
• D)you will need 11.8 g Cl₂ for complete reaction and will produce 49.0 g of AlCl_3.
• E)none of the above

Definitions:

Difference Threshold

The minimum difference in stimulation that a person can detect 50% of the time, also known as the just noticeable difference.

Retina

The light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information.

Retinal Disparity

A binocular cue for perceiving depth. By comparing retinal images from the two eyes, the brain computes distance— the greater the disparity (difference) between the two images, the closer the object.

Blind Spot

The point at which the optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there.
