the half-life of chlorine 36 is 400,000 years. 200,000 years is 1/2 of a half life.
in general, the formula to calculate the fraction of remaining amount is 1/2^n, where n represents the number of half-lives that have passed.
in this case, n=1/2, or 0.5, therefore the remaining fraction is 1/2^0.5. Use your calculator and you will find that this is 0.707, or about 71% of the original amount.
hope this helps
Hydrogen diffuses in faster than chlorine into the porous pot. Most of the chlorine remains outside the pot.
Chlorine is commonly used in pools for its effectiveness as a disinfectant. Here are several reasons why chlorine is used in pools: Disinfection: Chlorine effectively kills bacteria, viruses, algae, and other microorganisms present in the pool water. This helps maintain safe and sanitary swimming conditions by preventing the spread of waterborne illnesses and infections. Oxidation: Chlorine serves as an oxidizing agent, helping to break down organic contaminants such as sweat, body oils, urine, and sunscreen residues that can accumulate in pool water. This oxidation process helps keep the water clear and free of unpleasant odors. Algae Control: Chlorine also acts as an algaecide, preventing the growth of algae in the pool. Algae growth can make the water cloudy and unsightly, and chlorine helps to keep the pool water clear and aesthetically pleasing. pH Regulation: Chlorine can help regulate the pH level of the pool water by reacting with acidic or basic substances. Maintaining the proper pH balance is crucial for ensuring that the chlorine remains effective as a disinfectant and that the water is comfortable for swimmers. Convenience and Cost-Effectiveness: Chlorine is readily available, relatively inexpensive, and easy to use, making it a popular choice for pool sanitation among homeowners, pool operators, and maintenance professionals.
Organic Remains are remains from a living thing such as dead leaves or a dead tree. The Organic Remains are no longer in use but they have to be from something in nature.
Chloride Cl-: Ne,3s2,3p6 : has 1 valence electron accepted from metal XChlorine Cl : Ne,3s2,3p5 : neutral can donate 1, 3, 5 or 7 val. electrons, remains: 3p5->4,2,0 and 3s2->0 respectively, '->' means 'lowering to')Chlorine? Cl?: Ne,3s2,3p65 as in the questioned: unknown 65 is impossible,(mail my Mess.Board if you can give an other question.JdQ)
When it is like that, the remains decompose and form into dirt.
This fraction is 12,5 %.
1.5% remains after 43.2 seconds.
The half-life of Cs-137 is 30.08 years, so 0.0038 would remain after 241.84 years.
The fraction that remains is 1/8.
remains a gas
It remains an improper fraction.
