Using the equation above for radioactive decay, let's look at an example on how to calculate half-life decay: Bandages can be sterilized by exposure to radiation from cobalt-60, which has a half-life of 5.27 years. How much of a 10.0 mg sample of cobalt-60 is left after one, two...
Half-life Equation:Depending on the order, reactions have different half-lives. In certain cases, the half-life of a reactant is determined by the reaction's initial concentration. In certain situations, it is unaffected by the reactant's initial concentration....
However, many don't pose much of a threat because they have such long half-lives. The half-life of a radioactive isotope is the time it takes for half of the sample to react, or decay. This time can range anywhere from a portion of a second to thousands of years depending on the ...
To calculate the half-life, plug the value forkinto the half-life equation and solve. What is the half-life of a first-order reaction with a rate constant of1.70×10-4s-1? Express your answer with the appropriate units. b)What is the rate ...

This is contrasted with K-selection, in which ...
This is a separable differential equation, and can be solved to give Since we have the initial value , we can find C. can be found since we know that after 2.898 years there will be 5 grams. We know have a complete formula, which we can use to calculate out answer. Our amount...
