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

When naming the compound containing lithium and chlorine, change the suffix of the anion's name to?
When naming the compound containing lithium and chlorine, you would name it lithium chloride. The suffix of the anion's name (chlorine) remains as "-ide" when naming ionic compounds.
What is the atomic number of Cl2?
The atomic number of chlorine (Cl) is 17. When two chlorine atoms (Cl) combine to form Cl₂, the atomic number remains 17 because it represents the number of protons in the nucleus of each chlorine atom.
How are hydrogen and chlorine can be separated by passage through a porous pot?
Hydrogen and chlorine can be separated by passing them through a porous pot because hydrogen molecules are smaller and can diffuse faster through the pores of the pot compared to chlorine molecules. As a result, hydrogen will pass through the pot more rapidly, allowing for the separation of the two gases.
Why bromine does not react with aqueous potassium chloride?
Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.
If a chlorine atom has 17 protons and 18 neutrons what would its mass and atomic number be?
the atomic number would be 17 && the mass would be 35
What fraction of a sample of N 16 remains undecayed after 43.2 seconds?
1.5% remains after 43.2 seconds.
What is the fraction of a sample of tritium that remains undecayed after fifty years?
After 50 years, approximately 50% of tritium will remain undecayed in a sample. Tritium has a half-life of about 12.3 years, which means that the amount of undecayed tritium decreases by half every 12.3 years.
Cs-137 is produced as a waste product in nuclear fission reactors What fraction remains undecayed after 241.84 years?
The half-life of Cs-137 is 30.08 years, so 0.0038 would remain after 241.84 years.
What percent of a sample of As-81 remains undecayed after 43.2 seconds?
To determine the percentage of As-81 that remains undecayed after 43.2 seconds, you would need to know its half-life. As-81 has a half-life of approximately 46.2 seconds. Using the formula for radioactive decay, after one half-life (46.2 seconds), 50% would remain. Since 43.2 seconds is slightly less than one half-life, a little more than 50% of the sample remains undecayed, but the exact percentage requires calculations based on the exponential decay formula.
What happens to chlorine at 100 c?

What does an improper fraction become when it is reduced?
It remains an improper fraction.
What fraction of a sample remains after three half lives?
An eighth remains.
What is the significance of a half life of a radioisotope?
It tells what fraction of a radioactive sample remains after a certain length of time.
What do you mean by residual chlorine?
Residual chlorine refers to the amount of chlorine that remains in water after it has been treated. It is important for maintaining water quality by ensuring that harmful pathogens are destroyed and that the water remains safe for consumption. Monitoring residual chlorine levels is a common practice in water treatment facilities to ensure that water is properly disinfected.
What happens to the fraction if the denominator of a negative fraction increases?
The fraction becomes less negative. It remains a negative fraction but moves nearer to 0.
What happens when you multiply both the numerator and denominator of a fraction by 4?
The value of the fraction remains unchanged
After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
