Problem 7E

Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider the mixture of N2 and H2 shown in the accompanying diagram. The blue spheres represent N, and the white ones represent H. Draw a representation of the product mixture, assuming that the reaction goes to completion. How did you arrive at your representation? What is the limiting reactant in this case? [Section 3.7]

317 Color Vision Theories  Signaling: We attach meaning to color o Natural World: Color of berries to determine ripeness; Sick – pale skin; Traffic Signal – Green = Go  Perceptual Segregation: helps us segregate or separate stimuli effectively o Helping to separate objects by determining its boundaries through color Trichromatic Theory of color vision (Young-Helmholtz): retinal level  Color vision is dependent upon the activity of three different receptor mechanisms, each which is maximally sensitive to a particular wavelength (color) of light – red, blue, green (anatomical primaries).  Psychological Evidence: Color-matching Experiments: with color light participants mix the lights to get the lights presented to them – typically people will be able to get the result of the lights presented to them.  Anatomical Evidence: 3 Cones types: Red, Green, Blue-tuned Cones – helps us distinguish color Opponent-Process theory or color vision (Hering): LGN & Visual Cortex Level & Processing  Color vision is caused by opposing responses generated by pairs of colors: blue-yellow; red-green (and also black-white)  Psychological Evidence: o Psychological primaries: Red, Blue, Yellow; psychological “purity” of yellow (not mixed)  Green cannot be perceived to mixed with red o Negative afterimages: One that reveals the color pairing of red-green, blue-yellow, and black-white (afterimage: image that persist when stimuli
