What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
How can one determine the decay constant of a radioactive substance?
To determine the decay constant of a radioactive substance, one can measure the rate at which the substance decays over time. By analyzing the amount of radioactive material remaining at different time intervals, scientists can calculate the decay constant, which is a measure of how quickly the substance decays.
How do you calculate the decay constant for a radioactive substance?
The decay constant for a radioactive substance is calculated by dividing the natural logarithm of 2 by the half-life of the substance. The formula is: decay constant ln(2) / half-life.
How to calculate radioactive decay and its impact on the half-life of a substance?
To calculate radioactive decay, use the formula N N0 (1/2)(t/T), where N is the final amount of substance, N0 is the initial amount, t is the time passed, and T is the half-life of the substance. The impact of radioactive decay on the half-life of a substance is that it represents the time it takes for half of the radioactive atoms in a sample to decay.
What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
What if your cat is radioactive with the same halflife as carbon 14. how many years will it take for three fourths of your cat to degrade?

Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
What does not affect the half life or a redioactive decay?
External factors such as temperature, pressure, and chemical reactions do not affect the half-life of a radioactive substance. The decay rate of a radioactive isotope remains constant over time regardless of these external conditions.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
Half of the total amount of time it takes for all of a radioactive substance to decay is called the halflife of the substance?
okay
Is radioactive waste a pure substance or a mixture?

What is a radio substance?
A radioactive substance emit nuclear radiations.
