What is the molarity of the diluted solution when 1.00 L of a 0.250-M solution of Fe(NO3)3 is diluted to a final volume of 2.00 L? What is the molarity of the diluted solution when 0.5000 L of a 0.1222 M solution of C3...
In this study, Fe (NO3)3 was added in the initial stage and decomposed at a certain temperature. Owing to the strong adhe- sion between the eutectics and substrate, the Fe catalyst was not observed at the tip of nanobelts, rather acted as the root for the Figure 5 | Unit cell model...
If water is added to 50 mL of a 0.04 M solution so that it fills a 200 mL beaker, what is the final concentration? What is the final concentration of an iron(III) nitrate solution that is prepared by diluting 3.75 mL o...
that Fe3O4 nanoparticle was successively added with Tb(NO3)3 and H3BTC plus other necessary treatments, having been characterized through transmission electron microscope (TEM) and X-ray diffraction (XRD) so that its properties had been explored. Such the magnetic nanomaterial product (Fe3O4@Tb...
is adopted to carry out Fe loading on the acanthospheres, wherein a Fe(NO3)3 solution is prepared according to a certain mass percentage and a certain solid-to-liquid ratio, MnO2 is added to the Fe(NO3)3 solution, ultrasonic oscillation is performed, and water is evaporated; and the ...
This study was designed to investigate the catalytic oxidation performance of modified GAC by Fe(NO3)3and(NH4)2S2O8in the process of H2 O2.The effect of the initial concentration of H2 O2,initial dye concentration,catalyst dosage,initial pH and temperature on the reaction was discussed.The resul...
