It has been postulated that the reaction of nitric acid with calcium carbonate, namely, CaCO3(s) + 2HNO3(g) Ca(NO3)2(s) + CO2(g) + H2O(g), plays an important role in the atmosphere. In this study, transmission FTIR spectroscopy, diffuse reflectance UV-visible spectroscopy, transmission...
Ca2+(aq) + 6H2O(l) --> [Ca(H2O)6]2+(aq) + 6H2O(l) Eq. 2 Now comes the combustion: This is a project of AAS (atomic absorption spectroscopy), and I want to measure the absorbance for calcium when irradiated with a hollow cathode lamp. I am only interested in calcium so I i...

Currently I am working on a project related to calcium nitrate plant. I am given the task to calculate the CO2 emissions as the result of the reaction between nitric acid 54wt.% and calcium carbonate. I believe I need the reaction kinetics for this chemical reaction in order to compute the...
The model aerosols were generated by dry dispersion of Arizona Test Dust (ATD), SiOlt;subgt;2lt;/subgt;, and by nebulizing a saturated solution of calcium carbonate. The uptake of lt;supgt;13lt;/supgt;N-labelled gaseous nitric acid was observed in a flow reactor on the 0.2amp;ndash...

1-i-2) The reaction of a compound of formula (Ia) wherein W = - O-Rawherein Raand X1are as above defined, with a compound of formula (IIa) may be carried out in presence of a catalyst, such as N,N-dimethylamino pyridine (DMAP) or in the presence of DMAP and a Lewis acid suc...
Feces were dried under infrared light, pounded, and wet-ashed with nitric acid using Parr bombs (22). NIST reference material RM 8435 (whole- milk powder) was also subjected to identical treatment to verify accuracy of the analytical procedures and ashed with each bath of samples to ensure ...
Fresh plant leaves (500 mg) of each treatment were homogenized with 1.5 mL of TCA (tri-chloroacetic acid) (5% w/v) and centrifuged at 1200 rpm for 10 min. In 2.0 mL of diluted extract, 2 mL of thiobarbituric acid (TBA, 0.5% w/v) prepared in 1% butyl hydroxytoluene, 15% TCA, ...
(0.1 mM), and ascorbic acid (0.5 mM). The 1 mL supernatant was taken and the absorbance was measured at 290 nm and the activity was calculated at extinction co-efficient (2.8 mM−1cm−1). The CAT activity was measured using a mixture containing KP-buffer (100 mM, pH 7.0), ...
