A first-order reaction (A \to B) has a half-life of 30 minutes. If the initial concentration of A is 0.500 M, what is the concentration of B after 60 minutes? (Do not use a calculator to solve this problem.) Express your answer with the appropriate unit ...

needs to disintegrate or transform into a different substance. the principle was first discovered in 1907 by ernest rutherford. it is usually represented by the symbol ug or t 1/2 . it can also be referred to as the time taken for half of the reactions to complete or the time at which...
In calculating radioactive decay quantities, there are a couple of equations needed. One deals with the relationship between half-life of a substance and a rate constant k, and the other is the rate equation for first order reactions (radioactive ...
