Practice by predicting what would happen if the following underwent beta decay: (2 iv. Carbon -10 +
v. Cesium-137 +
vi. Thorium-234 +

See explanation and image attached

Explanation:

During beta emission, neutrons are converted into protons and electrons. The anti neutrino balances the spins.

When a nucleus undergoes beta emission, the mass number of the daughter nucleus produced in the process is the same as that of the parent nucleus but the atomic number of the daughter nucleus increases by one unit.

The product of the beta decay of the nuclides shown in the question is described in the image attached to this answer.

High-energy and unstable.

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
