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 +...
The density of the substance is the ratio between a specified mass of that substance and its corresponding volume. The density of a mass will work for any mass with a corresponding volume since density is specific to the substance in consideration. Densities have no unique unit ...
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...
