Measuring Quantities in Chemistry:Chemists over the ages have adopted various units to quantify chemical substances, from the so-called 'gram-equivalent' (related to equivalent weight), to grams, and in certain contexts, moles. If a substance needs to be weighed out in a chemical labor...
What is hypertonic in chemistry? A hypertonic solution is aparticular type of solution that has a greater concentration of solutes on the outside of a cell when compared withthe inside of a cell. What do you mean by hypertonic solution Class 9? A hypertonic solution isone that has a higher...
What is gravimetric analysis in analytical chemistry? Calculate the rate of reactant A from 200 to 400 seconds. How do you do volume to volume problems in stoichiometry? When we convert the concentration of ions (mg/L) to its equivalent weight by multiplying the ratio: number of the ion ch...

Unit of k is mol1−nLn−1S−1, where n is the order of the reaction. (ii) Half life period of a reaction(t1/2) : The half life of a reaction is the time period in which the concentration of a reactant is reduced to one half of its initial concentration. Show More ...
After the accident, analysis of residual fluid left in the transformer revealed the presence of polychlorinated dibenzodioxins and dibenzofurans at a concentration of 1.4 μg/g (expressed as 2,3,7,8‐tetrachlorodibenzodioxin "toxicity equivalents"). The analytical strategy and criteria adopted during...
Molecules were ranked for their potential patients/control discriminant capacity on the basis of the p-values of the difference between their concentration in patients and control groups (Fig. 5a). By applying an unsupervised two-cluster analysis to serum samples using these signature molecules, two...
