Write a balenced ionic equation for the reaction occurring when:(a) the addition of metallic aluminum to a copper(II) nitrate solution results in the precipitation of copper metal and the formation of aluminum ions in solution.(b) metallic copper is added to a dilute solution of nitric acid...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
While balancing a chemical equation, how can one decide which elements to balance first? What is the formula for finding out how many electrons an element has? What are the origins of the word "maniera"? What are some elements th...
The Yan model [32] is an empirical model represented by the equation:(9)CCi=1−11+CiQqYa∗m∗taYa Where aYa is an empirical parameter, qYa is the theoretical saturation adsorption capacity (mg g−1), m is the mass of adsorbent in the column (g), C is the concentration of ...
The intra-particle diffusion model is mainly used to determine the control steps of the adsorption process rate and is given by Equation (3). Qt = Kt1/2 (3) Based on the assumption that the rate of change of adsorbed solute with time is proportional to the difference in equilibrium ad...
(FeCl3) (anhydrous, powder, ≥99.99% trace metals basis), chitosan (medium molecular weight), polyvinyl alcohol (PVA), sodium alginate, sodium arsenate dibasic heptahydrate (Na2HAsO4·7H2O), sodium hydroxide (NaOH), boric acid (H3BO3), calcium chloride (CaCl2), and nitric acid 69% (HNO3)....
Iron (Fe) is a vital nutrient for the development of many plants. Therefore, enhancing plant performance and production in relation to Fe deficiency is becoming a serious challenge. In this work, we intended to survey the effect of seed pretreatment with salicylic acid (SA) on oxidative status...
Equation (2) was used to calculate the specific capacitance of the SSC (MDC-A nitrate/MDC-A nitrate) and ASC (MDMO iron/MDC-A nitrate). The specific capacitances of these two devices at various scan rates are shown in Figure 8d. It is obvious that the specific capacitance of the ASC...
After that, a few drops of nitric acid were added and kept in a refrigerator at 4 °C, to prevent any additional chemical reactions. 2.2.3. Characterization of Iron Oxide Nanoparticles The UV-Vis measurement was done by dispersing the IONPs in deionized water, followed by sonication for 10...
T2.3D-1.1 has genes that would allow it to perform the mixed-acid fermentation. Therefore, this strain could hypothetically grow fermenting pyruvate producing succinate, 2-oxoglutarate, acetate, ethanol and/or lactate. Past studies of the IPB have shown that there are relatively high concentrations...
