A kind of bacteria is encapsulated into a gel consisting of PNIPA. We want to incubate it with high concentration of sugar. Which kind of sugar should we use? If assume the bacteria can utilize every kind of sugar. A. High hydrated number sugar B. Galactose C. Mannose D. Insufficient in...
You have a solution that has a pH of 8 and need it to be a pH of 5. What do you do? What is the pH of a solution with a hydroxyl ion (OH-) concentration of 10^{-10}M? - pH 10 - pH 2 - pH 4 - pH 12 A solutio...
aYou are my everyth1ng. Dear.aThis life just to love you 亲爱: 您是一切对我,您是我的生活,我将爱您我的一生!!! [translate] aUse water and sand (Avoid bodily contact with water solution of a comparatively high concentration). 使用水和沙子(避免身体联络用比较高浓度的水解答)。 [translate] ...
FIELD: food processing industry, in process of cold concentration of water solutions, for example, juices. SUBSTANCE: water solution is given film mode of running in field of centrifugal forces and supersonic swirled stream of liquid with own temperature of boiling under atmospheric pressure below...
Therefore, from a thermodynamic point of view, it is expected that these reactions occur simultaneously when metallic magnesium is in contact with water and HF. The rate of each process will depend on the HF concentration. (1.2)Mg(s)+2H2O(l)→Mg(OH)2(s)+H2(g),ΔrG°=−359.3kJ/mol...
For ideal solution: For ideal gas: For real fluid: Means how active the component is in a solution compared with its standard state. For ideal solution at given T and P The the activity coefficient-- maybe considered as an effective concentration ,describing the deviation from ideal solution ...
If further solute is added to such a solution, it will not dissolve. Therefore, it can be said that a saturated solution is one that is in thermal equilibrium with the pure solute. The concentration of the saturated solution is a measure of the ability of a given substance to dissolve in...
1), various concentrations of NaCl (99.998%, Alfa Aesar) solution were prepared in deionized water; the measured conductivity of these solutions corresponds to a background concentration of monovalent ions of c0 ≈ 5 μM. The ionic strength of the various electrolyte solutions in our ...
However, at high concentration from 1 to 5 mM, the red shift of 390 nm peak is observed with the increase of the emission wavelength, while the position of 290 nm peak does not change with the increase of the emission wavelength. These results indicate the heterogeneity in the ...
The adsorption of the chemical components delays its concentration front with respect to the water saturation front (Patton et al., 1971; Entov and Polishchuk, 1975; Farajzadeh et al., 2016). Non-isothermal displacement is also modeled by a system of conservation laws. For these problems, ...
