How much thorium-234 will remain after 2 half lives?
After 2 half-lives, 25% of the original amount of thorium-234 will remain. This is because half of the substance decays in each half-life period.
How much of a radio active parent isotope remains after one half life has pass?
Half the original amount.
How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
25 gExplanation:Think about what a nuclear half-liferepresents, i.e. the time needed for an initial sample of a radioactive substance to be halved.
How much is half of 2 and a half gallons?
You cannot compare ounces (mass or weight) with gallons (volume).
How much amount of thorium is present in India?
India has one of the largest thorium reserves in the world, estimated to be around 25-30% of the global reserves, totaling about 846,000 metric tons. This makes India a key player in the development of thorium-based nuclear technology and energy production.
How much thorium-234 will remain after 2 half lives?
After 2 half-lives, 25% of the original amount of thorium-234 will remain. This is because half of the substance decays in each half-life period.
How much thorium in grams is there in 2 half lives?
To calculate the amount of thorium remaining after 2 half-lives, you use the formula: amount = initial amount * (1/2)^n, where n is the number of half-lives. If we assume the initial amount is 1 gram, after 2 half-lives, there would be 0.25 grams of thorium remaining.
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
How much electrons does Thorium have?
90 in ground state
How much does a ceramic bowl with thorium in it cost?
Ceramic bowls for kitchen, with thorium, doesn't exist.
How much of a radio active parent isotope remains after one half life has pass?
Half the original amount.
How much of a 100 g sample of thorium 234 will be unchanged after 48.2 days?
After 48,2 days the amount of Th-234 will be 25 g.
How much of the worlds thorium does the us possess?
United States has thorium reserves of approx. 160 000 t.
How much thorium is in bitumen?
The concentration of thorium in bitumen can vary depending on the source, but typically it is found in trace amounts. Studies have shown that thorium levels in bitumen are generally low and not considered a significant environmental or health risk.
How much of a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
What is the percentage of thorium in clay soil that is absorbed into the body?
When not mixed with clay, about 0.02% (depending on the type of thorium compound)of ingested Thorium is absorbed into the body but since Thorium is strongly adsorbed by clay, the absorption of ingested Thorium mixed with clay soil is negligible, much less than 0.02%.
A radioactive substance has has life of 5 days initial mass of 12kg how much the original isotope will remain after 10 days?
After 10 days, 1/2 of the original isotope will remain since its half-life is 5 days. This means 6kg of the original isotope will remain after 1 half-life, which remains the same after 10 days since another half-life has passed.
