Nitrogen calculations

Nonprotein kcaknitrogen ratio Ratio of carbohydrate plus fat calories in a volume compared to the grams of nitrogen (calculated as number of grams of protein divided by 6.25). 

The effective surface temperature of Titan is 98 K and the atmosphere is nearly completely nitrogen. Calculate the scale height for Titan s atmosphere. Comment on the diurnal variation of the scale height and the variation with altitude. 

These p/Tg-values show that the inductive effect of the C=C bond accounts for about one half of the reduction in the basicity of the enamine nitrogen atom, the other half being due to the mesomeric effect (Stamhuis et al., 1965). The localization energy of the lone pair on the nitrogen, calculated from the second Ap/iTa, is only about T6-1-7 kcal mole (6 7-7 l kj mol ). There are indications from the substituent effects on the stretching frequency of the C=CH2 bond that this group is an electron sink of the same kind...

Nitroglycerin is an explosive and is also used to produce other explosives, such as dynamite. Nitro is 18.5% nitrogen. Calculate the molecular mass of nitro. 

Values of the constants A, Band C [defined in eqns. (47) and (49)] for the atomisation of hydrogen, oxygen and nitrogen, calculated from the data of Stull and Sinke [13a], with = 1 atm...

Nitrogen calculated from carbon using given C N. 

A stream of humid air enters a condenser in which 95% of the water vapor in the air is condensed. The flow rate of the condensate (the liquid leaving the condenser) is measured and found to be 225 L/h. Dry air may be taken to contain 21 moIe% oxygen, with the balance nitrogen. Calculate the flow rate of the gas stream leaving the condenser and the mole fractions of oxygen, nitrogen, and water in this stream. 

A qualitative analysis of papaverine, one of the alkaloids in opium, showed carbon, hydrogen, and nitrogen. A quantitative analysis gave 70,8% carbon, 6.2%. hydrogen, and 4.1% nitrogen. Calculate the empirical formula of papaverine. 

Two tanks are initially sealed off from one another by means Of valve A. Tank I initially contains 1.00 fF of air at 100 psia and 150°F, Tank II initially contains a nitrogen-oxygen mixture containing 95 mole % nitrogen at 200 psia and 200 F. Valve A is then opened allowing the contents of the two tanks to mix. After complete mixing had been effected, the gas was found to contain 85 mole % nitrogen. Calculate the volume of tank n. See Fig. P3.16. 

Table 17 depicts data on the global biogeochemical cycle of nitrogen calculated by various authors. Describe these results and explain the possible reasons of data deviations. 

Figure 4. Calculated partial photoionization cross sections for the K-shell of N2 over a broad energy range. The dashed line represents twice the K-shell photoionization cross section for atomic nitrogen, calculated using a Hartree-Slater potential.

When 2.004 g of calcium is heated in pure nitrogen gas, the sample gains 0.4670 g of nitrogen. Calculate the empirical formula of the calcium nitride formed. 

Thus, the statistical film thickness for nitrogen calculated from the BET theory is ... 

The reported values of antibody in precipitates are the values of antibody nitrogen multiplied by the factor 6.25, the antibody nitrogen being the difference between total nitrogen in the precipitate and antigen nitrogen calculated...
