Answer:
The atomic mass of iodine-131 is 130.9056485 amu.
Explanation:
Beta-decay is the process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.
Energy released during beta particle emission = E
Mass of reactant = Mass of product + Δm
= Mass of beta particle + nuclide + Δm
Mass Beta-particle =
Mass of reactant =
=130.9051+0.000548579 amu + amu
= 130.9056485 amu
The atomic mass of iodine-131 is 130.9056485 amu.

Answer;
Fractional distillation
Explanation;
-Fractional distillation is one of the method that is used to separate mixtures. It is used for the separation of miscible liquids, for example water and alcohol.
-Fractional distillation is a distillation method that is used to separate liquids that dissolve in each other. It involves separating the components of a mixture by repeated distillations and condensations.
-The components in the mixture being separated by this method normally have different but close boiling points. For example a mixture of alcohol and water, they have different but close boiling points, thus during distillation alcohol condenses out as the first fraction followed by water.
When a sample of a gas is heated in a sealed, rigid
container from 200 degree Kelvin to 400 degree Kelvin, the pressure exerted by
the gas is increased by a factor 2. Heating any gas actually increases the
volume of the gas within a container. As the temperature of the gas rises, the
molecules of the gas start moving faster and start striking the walls of the
container in which it is kept with more force. The volume of the container
tries to expand to accommodate the fast colliding molecules of the gas.
