factors affecting choice of radiotracer techniques
Calculation of empirical formula The steps included in the calculation are as follows, (a) Divide the percentage (%) of each element by its atomic volume. This gives th
Which have the same number of S electrons as the d - electrons in fe2+
Q. Determine Mass to charge ratio of the electron? Ans. Eventually, Thomson was able to find the ratio of the electron's mass to its electrical charge (m/e). Regardless o
Correct configuration of Fe +3 [26] is: (1) 1s 2 , 2s 2 , 2p 6, 3s 2, 3p 6 , 3d5 (2) 1s 2 , 2s 2, sp 6 , 3s 2 , 3p 6 , 3d 3 , 4s 2 (3) 1s 2 , 2s 2 , 2p
Mechanism of reduction (b)
Osmotic pressure: Osmosis process is the movement of a solvent from a solution of lower solute concentration (higher solvent concentration) to one of the higher solute concentr
