The “screen” in a camera is flat, whereas the retina is curved.
Both eye and camera have limited fields of vision.
Both eye and camera use a transparent convex lens to form an image.
The sensitivity of the eye and the acuity are not constant over the retina, acuity and sensitivity being governed by the distribution of rods and cones on the retina; whereas the sensitivity of the camera film or electronic photosensitive light receptors is distributed evenly.
In a camera only air separates the screen from the lens; the eye is filled with liquid between the lens and the retina and this liquid adds to the refraction of the light.
Blood vessels come in front of the retina and therefore obscure the image, so the eye is in a state of minute motions to compensate for missing parts of the image; in a camera the screen is exposed only for a fraction of second usually to admit the required amount of light to form an image.
In the eye and the camera the lens produces an inverted image.
The eye produces an imperfect image containing chromatic aberration. The lens of a good camera produces minimal chromatic aberration.
The eye is only the start of the vision process and the brain has to learn to translate the image to make it meaningful. The process in the camera is mainly the result of optics directly.
The eye produces a chemical (visual purple) which improves and accommodates vision for different light levels. A camera is more limited for such accommodation. This is noticeable in pictures taken in artificial or low light.
As light level decreases, both eye and camera tend towards monochromatic images.
A camera can be made sensitive to frequencies of light outside the visual range, including ultraviolet and infrared. The eye is limited to a smaller range of light frequencies.
The camera can be used for lengthy exposures while the eye has to operate at a speed dictated by nerve impulses.

4). One mole of monoclinic sulfur at 25C was placed in a constant-pressure calorimeter whose heat capacity (C) was 1620 J/K. T
andre [41]

<u>Answer:</u> The enthalpy change of the reaction is -243 J/mol

<u>Explanation:</u>

The heat released by the reaction is absorbed by the calorimeter and the solution.

The chemical equation used to calculate the heat released follows:

q=c\times \Delta T

where,

c = heat capacity of calorimeter = 1620 J/K

\Delta T = change in temperature = 0.150^oC=0.150K   (Change remains same)

Putting values in above equation, we get:

q=1620J/K\times 0.15K=243J

<u>Sign convention of heat:</u>

When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.

For the given chemical reaction:

S\text{ (monoclinic)}\rightarrow S\text{ (orthorhombic)}

We are given:

Moles of monoclinic sulfur = 1 mole

  • To calculate the enthalpy change of the reaction, we use the equation:

\Delta H_{rxn}=\frac{q}{n}

where,  

q = amount of heat released = -243 J

n = number of moles = 1 mole

\Delta H_{rxn} = enthalpy change of the reaction

Putting values in above equation, we get:

\Delta H_{rxn}=\frac{-243J}{1mol}=-243J/mol

Hence, the enthalpy change of the reaction is -243 J/mol

Be sure to answer all parts. Consider the following balanced redox reaction (do not include state of matter in your answers): 2C
timurjin [86]

Answer:

The specie which is oxidized is:- CrO_2^-

The specie which is reduced is:- ClO^-

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

X\rightarrow X^{n+}+ne^-

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

X^{n+}+ne^-\rightarrow X

For the given chemical reaction:

2CrO_2^- + 6ClO^- + 2H_2O\rightarrow 2CrO_4^{2-} + 3Cl_2 + 4OH^-

The half cell reactions for the above reaction follows:

Oxidation half reaction:  CrO_2^- + 2H_2O + 4OH^-\rightarrow CrO_4^{2-} + 4H_2O + 3e^-

Reduction half reaction:  2ClO^- + 4H_2O + 2e^-\rightarrow Cl_2 + 2H_2O + 4OH^-

Thus, the specie which is oxidized is:- CrO_2^-

The specie which is reduced is:- ClO^-
