c1 = OH consumed to desorb (Moles OH/mole P)c2 = Adsorbent pore volume (L/Kg)c3 = Concentration of NaOH (Moles OH/L)c4 = Cost of NaOH ($/mole NaOH) C=((c1∗a2)+(c2∗c3))∗c4 For acid wash step:d1 = Acid consumption to release surface precipitate...
Both kinds of receptors have been identified to be expressed by bone cells to regulate purinergic signal. The normal ATP concentration is relatively low in extracellular space (10–100 nanomoles per liter) but relatively high in cytoplasm (5–10 micromoles per liter), and ATP can be released ...
ENERGETICS All types of chemical reaction involve changes in energy. When energy is emitted it can take a number of forms, but the most common form is as heat energy. Heat energy is called enthalpy. Enthalpy change is represented by the symbol ∆H. In general when bonds break energy has...
Let's use fluorine gas and helium as examples of calculating the number of atoms per gas molecule. Density of Helium = 0.1785 g/L Temperature = 273.15 K Pressure = 1.0 atm R = 0.0821 n = 0.044592 n*MM of He (4.00) = 0.1784 grams ...
where CaO* is CaO hosted in silicates only. The CIA index was calculated empirically by assuming the same mobilization abilities for Na and Ca. The CaO* was assumed to be equivalent to Na2O if the remaining number of CaO moles (after CaO corrected for phosphate using P2O5) is greater than...

a 1:1 alternating copolymer. However, in certain instances such as with styrene, etc., 1 or more moles of olefin may react with maleic anhydride. Olefinic compounds capable of copolymerizing with maleic anhydride include the following: vinyl aromatic compounds of the generalized formula ##SPC1#...
150g (5 moles) of 80% sodium hydride suspended in oil are dried three times each time with a 200 ml portion of absolute tetrahydrofuran, and then placed in a 2 l three-necked flask. 50 g (0.305 mole) of 1-methyl-β-D-ribofuranoside dissolved in 500 ml of absolute tetrahydrofuran are...
1. A compound of the formula (I): wherein G is CH or nitrogen atom; W is an oxygen atom, NR1 or S(O)n; n is 0, 1 or 2; R1 and R3 independently represent hydrogen atom or an optionally substituted group selected from alkyl, cycloalkyl, alkenyl, alkynyl, heterocyclyl, heterocycl...
