How long does ozone take to decay back to oxygen?
Ozone is decayed back to oxygen. It depends on how the ozone is being converted.
How long will it take 50 grams of a substance to decay to 10 grams if the rate of decay is k -0.345?
To determine how long it will take for 50 grams of a substance to decay to 10 grams with a decay constant (k = -0.345), we can use the exponential decay formula: [ N(t) = N_0 e^{kt} ] where (N_0) is the initial amount (50 grams), (N(t)) is the amount at time (t) (10 grams), and (k) is the decay constant. Rearranging the equation and solving for (t): [ 10 = 50 e^{-0.345t} ] Taking the natural logarithm of both sides and solving for (t) gives: [ t \approx \frac{\ln(5)}{-0.345} \approx 5.03 \text{ time units} ] Thus, it will take approximately 5.03 time units for the substance to decay from 50 grams to 10 grams.
How long does it take a radioactive atom to decay?
The time it takes for a radioactive atom to decay can vary significantly depending on the specific isotope. This is measured in terms of a half-life, which is the time it takes for half of the radioactive atoms in a sample to decay. Half-lives can range from fractions of a second to billions of years.
How long does it take for 75 of an original 100 silver atoms to decay?
The decay rate of atoms is typically quantified by a half-life, which is the time it takes for half of the original atoms to decay. If we assume a constant decay rate, we can estimate that it takes approximately 3 half-lives for 75 of the original 100 silver atoms to decay. If the half-life of the silver isotope is 1 hour, then it would take approximately 3 hours for 75 of the atoms to decay.
What happens to a body in a casket buried?
When a body is buried in a casket, it undergoes a natural decomposition process over time. Initially, the body may be preserved for a period due to the airtight seal of the casket, which limits exposure to air and moisture. Eventually, bacteria and microorganisms break down the tissues, leading to the release of gases, and the body will decompose into organic matter. Depending on environmental conditions and the materials of the casket, this process can take several years to decades.
How long does it take for a tooth to decay in soda?

How how long does it take for a body to decompose?

How long does it take for an adult human skeleton to disintegrate?
If a human is buried in the ground in a quality coffin, it could take as much as 50 years for the body to decompose. If the body is buried in a cheap casket, decomposition and exposed to the elements, decomposition happens very quickly.
