Why would tert-amyl chloride turn acidic after several weeks.
koban [17]

The acidic level is given by the amount of hydronium in a specific solution.

Therefore, the tert-amyl chloride would turn acidic because the quantity of hydronium will increase, which decreases the pH level.

If you have 200. 0 g of radioisotope with a half-life of 5 days. How much isotope would remain after 15 days?
Katen [24]

If you have 200. 0 g of radioisotope with a half-life of 5 days. 25g of isotope would remain after 15 days

Isotopes are members of an element family that have the same number of protons but differ in the number of neutrons. The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus. Carbon, for example, has six protons and has atomic number 6.

Radioisotopes are elemental radioactive isotopes. They can alternatively be defined as atoms with an unstable neutron-proton combination or surplus energy in their nucleus.

Radioisotopes are critical components of medical diagnostic techniques. They can be utilized for imaging to examine the dynamic processes taking place in various sections of the body when combined with imaging devices that register the gamma rays emitted from within.
