In general, the diffusion coefficient is inversely proportional to pressure. This is also an observed fact: gas production rates from coal seams tend to increase as the reservoir pressure goes down.
0.326 moles of gas
Explanation:
Knowing the volume of a gas at standard temperature and pressure (STP) we may calculate the number of moles of the gas using the following formula:
number of moles = volume / 22.4 (L /mole)
number of moles of gas = 7.3 (L) / 22.4 (L /mole)
number of moles of gas = 0.326 moles

Answer:
through ecological science
Explanation:
Ecological scientists study organism-environment interactions across ... Plant life clothes much of Earth's land surface, providing structure to ecosystems (e.g., ... Figure 1: A flock of Ibis visits a flooded rice field in California.
The correct option is B.
A buffer refers to an aqueous solution which resist changes in pH when acids or bases are added to it. Also addition or removal of water from a buffer system does not change the pH of the system significantly. Buffers typically are made up of pairs of weak acid and their conjugate base or pairs of weak base and their conjugate acids. Maintaining the ideal pH is very important in living organisms, blood buffers help living organisms to maintain constant blood pH.
Explanation:
The maximum wavelength of light that can cause this reaction is 420 nm.
a) The wavelength given lies in the range of visible light range that is from 400 nano meters to 700 nano meters.
The light with wavelength of 420 nm is found in the range of visible light.
b)The maximum strength of a bond :
where,
E = energy of photon = Energy required to break single molecule of nitrogen dioxide
h = Planck's constant = 
c = speed of light = 
= wavelength = 
Energy required to break 1 mole of nitrogen dioxide molecules:
(1 J = 0.001 kJ )
285.13 is the maximum strength of a bond, in kJ/mol, that can be broken by absorption of a photon of 420-nm light.
c) the photodissociation reaction showing Lewis-dot structures is given in an image attached.
