Answer: radon (atomic mass 222 amu
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:
atomic mass of krypton= 83.8 amu
atomic mass of argon= 39.95 amu
atomic mass of xenon = 131.3 amu
atomic mass of radon= 222 amu
Thus as atomic mass of radon is highest, its rate of diffusion is slowest.
I was on the phone to see if you wanted me a couple questions and I would be able answer questions on how
Oxygen is a liquid under one atmosphere. the boiling point of a substance is the temperature at which vapor pressure of a liquid is equal to the pressure of the surrounding liquid. the boiling point of oxygen at this case is 90.0k. Therefore the temperature of oxygen is 90-273= -183 celsius scale
This all depends on lots of independent variables such as force used to roll the ball, wind resistance, etc. With no variables included, they would both move at the same velocity.
The process in which energy is converted from solar to chemical and then one form of chemical to another form is photosynthesis. It is a process carried out by the plant to make food. The leaves of the plant take in sunlight, water from the soil and carbon dioxide from the air to produce glucose and oxygen.
