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.) Ex
The data presented in this calculator concerns the temperature of 25 °C. Knowing the potentials of half-cells (cathode and anode), we can calculate the potential of a cell composed of them: E∘=Ecathode∘−Eanode∘E∘=Ecathode∘−Eanode∘ where: E∘E∘ - standard cell ...
If the half-life of a first order reaction is 137 minutes, what is the rate, k? How is half-life used with absolute dating? How do you calculate the half-life of an isotope? When calculating a half-life, does this only occur with beta decay?
