Answer:
Kinetic energies of all the gases are same.
Explanation:
The average kinetic energy of molecules of a gas is given by the formula:
K.E = (3/2)KT
where,
K.E = Average Kinetic Energy of the molecule
K = Boltzman's Constant = 1.38 x 10^-23 J/K
T = Absolute temperature of gas
Since, all the gases are in a mixture, and the temperature of the gases must be same and equal to the temperature of mixture.
Therefore, all the terms in the formula are constant and the <u>Average Kinetic Eenergies of all the gases in the mixture (namely, Neon Ne, Krypton Kr, Radon Rn), equal.</u>
Hi!
The Ionosphere, also known as the Ozone Layer, is a layer in the atmosphere that is home to Ozone gas. This layer protects earth from ultraviolet (UV) radiation.
Hope this helps :)
Answer:
all atoms of a given element have the same number of protons but may have different masses
Explanation:
After the discovery of isotopes, scientists were able to conclude that all atoms of a given element have the same number of protons but may have different masses.
Isotopes are atoms of an element that have the same atomic number but different mass number.
The atomic number is the number of protons within an atom.
Mass number is the number of protons and number of neutrons.
Therefore, all atoms of a given element have the same number of protons but different mass.
the answer is A. I (iodine)
no worries
