Dalton s law Dalton s law states that in a mixture of gases (A + B + C. . . ) the total pressure is simply the sum of the partial pressures (the pressures associated with each individual gas), decomposition reactions Decomposition reactions are reactions in which a compound breaks down into two or more simpler substances, diamagnetism Diamagnetism is the repulsion of a molecule from a magnetic field due to the presence of all electrons in pairs, dilute Dilute is a qualitative term that refers to a solution that has a relatively small amount of solute in comparison to the amount of solvent, dimensional analysis Dimensional analysis, sometimes called the factor label method, is a method for generating a correct setup for a mathematical problem. 

Hyper saturating your body with fluids will dilute metabolites possibly below the 50 ng/mL threshold, depending on your metabolism. Be aware that creatinine levels are often tested, and will show that the sample has been diluted. Diluting your sample will also produce clear urine, with virtually no yellow color. They will assume that you ve diluted your sample, and they may reject your sample on the basis of color alone. It s only necessary to start drinking just before the test. Those who drown themselves in fluid days before a test are only causing unnecessary discomfort. Those who stay up...

Crankcase Dilution Dilution of lubricating oil in the oil pan or sump of an engine by fuel which has entered the crankcase. 

The sensitivity range for the colorimeter, following the method above, is 0-20 ppm hours NO2. If a sampler exceeds 20 ppm hours, it can be diluted with an additional, known aliquot of azo dye reagent and analyzed again. This value is multiplied by the dilution factor to arrive at the accurate ppm hour value. By performing a one fold dilution (dilution factor 2), the sensitivity range of the colorimeter can be extended to 40 ppm hours NO2. A dilution flask is supplied in case of the need for further dilutions. 

In addition to maltose, beer confabs small proportions of other reducing substances, which are however usually calculated as maltose. The gas-free beer is suitably diluted (dilution of 25 c.c. to 100 c.c. generally suffices) and the reducmg substances determined by means of Fehling s solution, either gravimetrically or volumetrically ...

Phosphate-buffered saline (PBS) For a 1-L lOX stock solution of PBS, dissolve 2.56 g NaH2P04-H20 and 11.94 g Na2HP04 in 500 mL distilled H2O (dH20) by stirring and then adjust the pH to 7.2. Add 87.66 g NaCl, and bring to a final volume of 1 L. Store the stock solution in the refrigerator and warm to dissolve the salts before dilution. Dilute 10-fold with dH20 for use. 

Acids, diluted Diluted acids are acid preparations, usually 5-10% strength, used for both internal and external medicines. Acids became official with the first United States Pharmacopoeia (1820). The term comes from the Latin meaning sharp or sour. ...

Heats of Dilution. Diluting with an additional 75 lb water will produce 100 lb dilute solution with a total acid content of 8 per cent and an enthalpy of —21 Btu per lb, or a total enthalpy of —2100 Btu. Hence the total heat evolution on diluting the original 10 lb to 100 is 115 Btu per lb. The straightness of the enthalpy curve between 8 and 0 per cent total acid shows that any further addition of water will not change the total enthalpy further. Hence 115 Btu per lb can be taken as the heat of dilution of the mixed acid at 32°F, the heat evolved on diluting it at this temperature to zero acid concentration. 

The German "Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area, Working Group Analytical Chemistry" has developed a continuous nebulization FAAS method for copper in serum based on a 1 -r- 1 dilution (dilution depends on the applied burner system) with a determination limit of 0.1 mg/L At a mean copper concentration of 1.24 mg/L the within batch precision was 2.4% and the day-to-day precision 3.2% (Winter and Schaller, 1985). Accuracy was checked against certified reference materials. The method was applied on fortified samples from a serum pool of healthy persons and compared by a GF/ AS method developed and tested at the same time (Angerer et al., 1985). The FAAS method is still in successful routine use in a number of German laboratories because of its reliability, simplicity and speed (Schaller, 1993).
