Question
Chapter 4.4, Problem 25SSC
Interpretation Introduction
Interpretation:
The stability gained by an unstable atoms needs to be explained.
Concept introduction:
Atom is the smallest particle in the element that can neither be created nor destroyed. It consists of protons, neutrons and electrons.
Expert Solution & Answer
Answer to Problem 25SSC
Unstable atoms undergo a series of radioactive decay until they become a stable element.
Explanation of Solution
An atom is unstable if the nucleus has excess of energy due to the presence of excess neutrons or protons. These are also radioactive atoms. Radioactive atoms emit radiation because their nuclei are unstable.
Unstable nuclei lose their energy in a spontaneous process by emission of radiation. This process is known as radioactive decay. Unstable atoms undergo radioactive decay until a stable atoms, possibly of a different element is formed.
Conclusion
Hence, an unstable atom becomes stable by undergoing radioactive decay until it becomes an element.

- You wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2. (a) How much NaOCI (kg) should you add? (Note: the equivalent weight of NaOCl is based on the reaction: NaOCl + 2H + 2 e→CI + Na +H₂O.) (10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal?
