Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative ...
Relative standard deviations, considering five replicates of sample submitted to the proposed methodology, were 1% for Cl and Br, and 2% for I, when a closed vessel microwave was used. The results for Cl were in good agreement with the certified values (90% confidence level). For Br, ...
Well-resolved He I photoelectron spectra of atomic chlorine and bromine have been obtained without serious background electrons, giving rise to relative photoelectron intensities associated with differential photoionization cross sections at an angle of 90° with respect to the incident 584 radiation.DOI...
Using 50 mmol L− 1 NH4OH as absorbing solution, recoveries close to 100% for bromine and iodine were obtained as well as a low relative standard deviation (5%). No statistical difference (t-test, 95% of confidence level) was observed between the values obtained by ICP-MS after MIC ...
