What is the Eyring equation and what is it used for? Consider the potentiometric cell Ag (s) | AgCl (s) | Cl^- || Fe^{2+} (aq), Fe^{3+} (aq) | Pt(s) If E_{cell} = 0.703 Then what is the ratio of [Fe2+]/[Fe3+]? In chemistry, what does...
It is an intensive property that does not depend on the volume or mass of substance present. We can calculate for the density of liquids by weighing the liquid and measuring its volume. Following this, we take the ratio of the mass of the liquid and the volume of the liqui...
Calculate the number of moles of magnesium that are needed to completely react with 2.16 moles of HCl. Mg + 2HCl arrow MgCl2 + H2 If you used 0.500 g of Mg and an excess of HCl, how much hydrogen gas should be produced at STP? The reaction is: Mg + 2HCl to MgCl_2 + H...
Polymers are all around us, a fact that we cannot deny. Polymers are used by everyone of all ages. Man has used natural polymers throughout history, but it is only in the last 60 years that we have been able to make our own synthetic polymers. Polymers have been used vastly in many ...
It has been shown that cells grown in the presence of high CO2 have a lower PSI/PSII ratio compared to air-grown cells [51]. Cells grown at high CO2 concentrations therefore mimic cells exposed to short (up to 6 h) high light treatment [52]. Cells exposed to 500 μmol photons m−...

Of these tested substances, NaCl, KCl, glucose, sucrose, citric acid, NaH2PO4, CaSO4, Cr(VI), NaIO4, CaCl2, CuCl2, KI and MgCl2 exhibited lower fluorescence response as compared to BH, while SDS, isatin and FeCl2 had a little obvious effect on the fluorescence recovery ratio (I-I0)/I...
Briefly, 5 u l of undiluted first RT-PCR product was added to a reaction mixture consisting of 3 u l of 25mM MgCl2, 2 u l of 10mM dNTPs, 0.5 u l of Taq Polymerase (5U/ul), 5 u l of 10X Taq buffer, 1 u l of each type specific primers P[1], P[5] and P[11] and an...
However, the ratios are not exactly 1.8 but are generally higher, which may mean that there are traces of RNA present in the sample since the expected value for RNA is around 2.0. Finally, the purity check regarding the A260/230 ratio is significantly lower than the expected 1.8 for …...
