C. the square root of the mass of the particles.
<h3>Further explanation </h3>
Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
From this equation shows that the greater the mass of the gas, the smaller the effusion rate of the gas and vice versa, the smaller the mass of the gas, the greater the effusion velocity.
So if both gases are at the same temperature and pressure, the above formula can apply
884 pounds of carbon dioxide are emitted in 400 litres.
What is a pound?
The pound is defined as the basic unit for weight in the Foot Pound Second (F.P.S) system and is equal to 16 ounces.
To convert a litre measurement to a pound measurement, multiply the volume by 2.204623 times the density of the ingredient or material. Thus, the volume in pounds is equal to the litres multiplied by 2.204623 times the density of the ingredient or material.
One litre of water weighs approximately 2.21 pounds.
So 400 liter = 400 liter x 2.21 pounds
= 884 pounds
Hence, 884 pounds of carbon dioxide are emitted in 400 litres.

Answer:
Compound
Explanation:
It has a definite composition throughout and can be made of more than one type of element.
Answer:
E = hV
Explanation:
Hello,
Photo electric effect theory was borne out the the confusing if light was either a particle or a wave. However Albert Einstein came up with a theory that light was a particle and each particle carry a certain amount of energy referred to as photons.
He used Max Planck's idea and theorized that since light is made up of photon, when each photon comes in contact with the surface of a metal, the energy is transferred to the electron.
E = hv
E = energy of the photons
h = Planck's constant = 6.626×10⁻³⁴Js
v = frequency of the photon in Hz
