Answer:
Pupil, Cornea, Retina, and Lens
Explanation:
rate 1 of the reaction = k [A]²
rate 2 of the reaction = k [A/2]² = k[A]² /4
We can see that rate of the reaction will be 4 times less.

Answer:
The ideal gas equation
Explanation:
The ideal gas equation is derived from the combination of three gas laws:
- Boyle's law
- Charles's law
- Avogadro's law.
The ideal gas law is expressed mathematically as: PV=nRT where:
P is pressure
V is volume
n is the number of moles
R is the ideal gas law
T is temperature.
To obtain the combined gas law, we assume that n=1 and this gives:
= R
Therefore:
= 
Atmosphere is made of a mixture of gases. Each individual gas exerts a pressure known as the partial pressure.
The sum of the partial pressures exerted by each gas in the mixture is equal to the total pressure exerted by the mixture of gases as a whole.
The partial pressure depends on the composition of the gas in the mixture.
In this case the total pressure - 870 mmHg
21% of atmosphere is oxygen
partial pressure of Oxygen = 870 mmHg x 21% = 182.7 mmHg
