How long will it take for 75\% of the atoms of a certain?

How long will it take for 75\% of the atoms of a certain?

How long will it take for 75\% of the atoms of a certain radioactive element, originally present to disintegrate? The half-life of the element is 10 days.

What is the half-life of a radioactive substance if 75 of its given amount disintegrate in 60 minutes?

45 min.

What is the half-life of a radioactive substance?

half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive …

Which isotope below has the highest nuclear binding energy per gram?

Nickel-62 has the highest binding energy per nucleon of any isotope. If an atom of lower average binding energy is changed into two atoms of higher average binding energy, energy is given off. Also, if two atoms of lower average binding energy fuse into an atom of higher average binding energy, energy is given off.

What is the half life of a compound if 75 percent of a given sample of the compound decomposes in 60 minutes?

So to multiply by t half equal to 60 minutes, Antifa from here will be called to 30 minutes. No. So therefore the half life period off the compound is 30 minute.

What is the half life of a radioactive substance?

What is the half-life of a compound if 75 percent of a given sample of the compound decomposes in 60 min assume first order kinetics *?

What is the half-life of an unknown compound if 17.0\% of the compound decomposes in 150 minutes via a first order process?

The half-life is (b) 12 minutes.

What is the half-life period of a radioactive substance is 87.5 of it disintegrates in 40 minutes?

k=2.303tlogaa−xk=2.30340logaa−0.875a=2.30340loga0.125a=2.30340log8=0.051 mint12=0.693K=0.6930.051=13.58 min. 87.5 \% of the substance disintegrated in 45 minutes (first order reaction) .

Do all radioactive elements have a half-life?

Radioactive elements have a half-life. Half-life occurs naturally in some of the radioactive elements while it could be artificially stimulated in some other elements. The half life of any given element is the time that is required for one half of the sample to decay.

How long does it take for a radioactive substance to decay?

Each and every radioactive element has its own half-life. For instance, 238 U has a half-life of 4.5billion years. A radioactive substance has a half-life of 20 minutes. If we begin with a 500 g sample, how much of the original sample remains after two hours?

What is the half-life of an isotope?

This time frame, where statistically half the atoms decay is called the half-life. So let’s say we have 1,024 grams of a pure unstable isotope. After one half-life half of the atoms will have decayed. Cool.

How long does it take for a radioactive sample to disintegrate?

Fraction of the radioactive sample disintegrated in 60 minutes = 75\% = 0.75 = ¾The fraction of the radioactive sample remaining un-disintegrated after 60 minutes = 1 – ¾ = ¼ = (½)²So 60 minutes equals two half-lives of the given radioactive sample.Therefore the half-life of the sample = (60/2) minute= 30 minute. 30 minutes.
