How much of a 100 gram sample would remain unchanged after two hours?
This would depend on the specific sample and its stability. Without additional information, it is not possible to determine how much of the sample would remain unchanged after two hours.
How much of a 100 gram sample would remain unchanged after 2 hours?
To determine how much of a 100 gram sample would remain unchanged after 2 hours, it is necessary to know the specific decay rate or change process of the sample. For example, if the sample undergoes a decay process with a known half-life, you can calculate the remaining amount using the formula for exponential decay. Without this information, it's impossible to provide an exact answer. In general, if no decay occurs, the entire 100 grams would remain unchanged.
What is the total mass of a 10. gram sample of 42k that will remain unchanged after 12.4 hours?
To determine the remaining mass of a 10-gram sample of (^{42}\text{K}) after 12.4 hours, we need to know its half-life. The half-life of (^{42}\text{K}) is approximately 12.36 hours. After 12.4 hours, which is slightly more than one half-life, the mass will be reduced to about half of the initial mass. Thus, approximately 5 grams of the original 10-gram sample will remain unchanged after 12.4 hours.
The human egg is prime for how many hours?
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.
What Contains 22 protons and 21 neutrons.?
An element with 22 protons is titanium (Ti), as the number of protons determines the atomic number of an element. With 21 neutrons, this specific isotope of titanium is titanium-43 (Ti-43). This isotope is radioactive and has a half-life of about 22.3 hours.

Determine the amount of time it takes for three fourths of a radioactive sample of an isotope of bromine to decay the half-life of the isotope is 16.5 hours?
The half-life of the isotope is 16.5 hours, so it takes 16.5 hours for half of the sample to decay. To find the time it takes for three fourths of the sample to decay, you would calculate 2 half-lives (2 x 16.5 hours) as three fourths is equal to 1.5 times the original amount (1 + 0.5). Therefore, it would take 33 hours for three fourths of the sample to decay.
What is the amount of time it takes for three fourthsof a radioactive sample of an isotope of bromine to decay if the half life of the isotope is 16.5 hours?
It takes one half-life for half of the radioactive sample to decay. Since half of the sample has decayed after 16.5 hours, it will take another 16.5 hours for the remaining half to decay, totaling 33 hours to decay three fourths of the original sample.
Molybdenum-99 has half a half-life of 66 hours. after 132 hours how much of an initial sample of 10 ci of mo-99 would remain?
After 132 hours, 1/4 of the initial sample of 10 Ci of Mo-99 would remain. Since the half-life is 66 hours, after 66 hours half of the sample would remain (5 Ci), and after another 66 hours (totaling 132 hours), half of that remaining amount would be left.
How much Cu -64 would remain from 2mg sample after 12 hours?
Copper-64 (Cu-64) has a half-life of approximately 12.7 hours. After one half-life (12.7 hours), half of the original sample would remain. Therefore, from a 2 mg sample, after 12 hours, approximately 1 mg of Cu-64 would remain, as it has not yet fully completed one full half-life.
How much Cu-64 would remain from a 2 mg sample after 12 hours?
1mg
How much Cu-61 half-life about 3 hours would remain from a 2 mg sample after 9 hours?
