• m = mass of solute in grams • V = total volume of solution in Liters • Eq = equivalent weight Example: How will a 2N solution of H3PO4 be prepared? Using the formula, Normality (N) = m /V × 1 / Eq • N = 2 • m = unknown • V = 1 liter • Eq = ...
The study demonstrated that the thrombus has a complex structure, which includes slender platelet aggregates (strings) that converge into a dense mass near the apex and abruptly end in the expansion region, forming a thrombus with microchannels that allow some blood flow through the main body of...
Find the ionic strength of (Electrochemistry): i. 0.05 \ mol \ dm^{-3} \ KCl(aq) ii. 0.05 \ mol \ kg^{-1} LaFe(CN)_6(ag) Give detail explanation. (eq. why does CN have a charge of 3 and why isn't the mass \tiems 6 for the 3 ions?) How do you find ionic equations...
Which of the following is true for a cell made of Pb(s)|Pb2+(aq) and Al3+(aq)|Al(s)? a. The concentration of Al3+ decreases. b. The concentration of Al3+ increases. c. The concentration of Pb2+ increases. d. The mass of the lead electrode decreases. e. Th...
The resulting Qb-(Hpg16)180 was characterized, including by mass spectrometry and dynamic light scattering (Fig. 3 and see Supplementary Methods and Supplementary Fig. S1), demonstrating the introduction of the Hpg amino acid into the sequence. On the basis of previous results42,43, Qb-(Hpg16...
An acetonitrile gradient (from 9% to 35% acetonitrile in water with 0.1% formic acid) at a flow of 500 nL/min was used to elute the peptides in 50 min. Sample were analyzed by a Q Exactive Mass Spectrometer (Thermo Electron, San Jose, CA, USA) at spray voltage of 3.5 kV, and ...
due to the limited observational sensitivity of currently available instruments. Malhotra & Rhoads (2002) pre- sented their theoretical estimates that large Lyα equiv- alent widths [EW 0 > ∼ 150 ˚ A for a Salpeter initial-mass
Isotope ratios were determined on an ELEMENT-2 high-resolution inductively coupled plasma mass spectrometer (ThermoFinnigan) using an Aridus Desolvating Sample Introduction system with a T1H nebulizer (Cetac Technologies). The ELEMENT-2 was run in low-resolution mode using the method developed by Fi...
The single step reaction of 2-pyridinecarboxaldehyde, 3-nitro aniline and anhydrous cobalt dichloride affords only the tcc-(LNO21)(LNO22)CoIICl2 as the product which is characterized by IR, Mass, UV–Vis spectra and magnetic susceptibility measurements. Single crystal X-ray structure ...
Sufficient mixing between phases is important to encourage mass transfer. As will be understood by one well practiced in the art, other polymerization procedures may also be employed. In particular, the use of the perfluorinated hydrocarbon of low molecular weight as part of the polymerization ...
