Write the formula for the complex ion formed by the metal ion Cr3+ and six NO2- ions as ligands. Decide whether the complex could be isolated as a chloride salt or a potassium salt, and write the formula for the appropriate salt
The half-life for the process 238U→206Pb is 4.5×109yr. A mineral sample contains 61.0 mg of 238U and 14.5 mg of 206Pb. What is the age of the mineral? To calculate the age of the mineral, begin by rearranging the first-order relationship between the half-life, t1/2, and the decay constant to solve for the decay constant, k. k=0.693/t1/2 Then, use the following formula to solve for the age of the mineral, t: t=−1klnNtN0 where N0 is the original amount of 238U...
