35.00 mL of a solution containing HCl is titrated with 45.00 mL of a 0.11 M solution of NaOH. What is the molarity of HCl in the solution? 15.0 mL of 0.45 M NaOH is neutralized by 13.7 mL of an HCl solution. What is the molarity of the HCl so...
Brown plate-shaped crystals were observed after about 6 days in the reservoir solution containing 0.1 M Tris–HCl (pH 7.0) and 25% w/v PEG3350 (for FabX) or 0.1 M HEPES (pH 7.0) and 20% w/v PEG 8000 (for FabX–holo-ACP). For FabX–octanoyl-ACP complex, 35 mg/ml ...
Appropriate amounts of isotope spike solutions containing 105Pd, 101Ru, 193Ir, and 194Pt were added to the samples. PGEs were concentrated by Te-coprecipitation in the decomposed solution. To minimize possible interferences, Cu, Ni, Zr, and Hf were removed using an ion-exchange resin ...
If a single-membrane structure is used, it would be difficult to use an all-alkaline electrolyte with a single bifunctional air electrode: as the membrane is sandwiched by two electrodes, if the cathode is flooded with KOH solution, it will have a low oxygen feed during discharge (ORR reacti...
After 30 min elapsed, a solution of PQXOH in EtOH was added to sol B. Sol formation reactions were stopped after 3 h. After cooling to room temperature, both sols were filtered and set aside for 24 h. The sol A was colorless, whereas the sol B was orange. Sol layers were deposited...
Ca2+- and HCO3−/CO32−-containing solutions were mixed in the reactor in presence or absence of mineral substrates (quartz, mica). Table 1. Precipitates and induction periods of formation as a function of solution conditions. Activities and supersaturations (Ω) were calculated using PHREEQC...
aPredict the partial vapour pressure of HCl above its solution in liquid germanium tetrachloride of molality 0.10 mol kg−1. For data, see Exercise 5.3a. 预言HCl部份汽压在它的解答之上在molality液体锗四氯化物0.10 mol kg−1。 为数据,看锻炼5.3a。 [translate] ...
Step by step video & image solution for HCl was passed through a solution of CaCl_(2), MgCl_(2) and NaCl which of the following compound(s) crystallises? (A) Only MgCl_(2)(B) NaCl,MgCl_(2) and CaCl_(2)] (C) Both MgCl_(2) and CaCl_(2) (D) Only NaCl by Chemistry expert...
What would happen to the color of a dilute solution containing FeCl{eq}_4 {/eq} if you added concentrated HCl?HClIt is a colorless liquid having a molar mass of 36.46 g/mol. It is corrosive in nature having a unique pungent smell. Its solution in wate...
1). Persistent euxinia then developed in Horizon D, as well as in Horizon F, the base of which coincides with the LOMEI-2 interval, with Horizon E marking ferruginous (anoxic, Fe-containing) deposition in the interim. Importantly, this ocean redox history is broadly consistent with the ...
