Compare the length of a column of mercury to that of a column of water required to produce a pressure of 1.0 bar. the densities of mercury and water at 0C are 13.459g/cm^3 and .99987g/cm^3
calculate the osmotic pressure associated with 50.0 g of an enzyme of molecular weight 98,000 g/mole dissolved in 2600 mL
the sandals in disintegrations per minute per gram? Assume the original activity was 15.3 disintegrations per minute per gram.
A 0.5 M solution of hydrogen sulfide (H2S) contains 0.15 M nickel chloride NiCl2, and 0.35 M mercury nitrate Hg(NO3)2. The pH of this solution is made very acidic through the use of HCl so that all ions are in solution
If a photon has a wavelength of 412.2 nm, what is its energy in J, frequency in s^-1, wavenumber in cm-1, and linear momentum in kg m/s
The element is so highly unstable that no observations of its properties have been possible. Based on its position in the periodic table, propose two different reasonable valence electron configurations for this element.
Explain why a mercury-in-glass thermometer with a uniform-bore capillary that is correct at 0 celsius and 100 celsius read 49.9 celsius when the temperature is actually 50 celsius.
The nitrite ion (NO2-) is commonly determined by a colormetric procedure using a reaction called the Griess reaction. Im this reaction the sample containing nitrate is reacted with sulfanilimide
Ionization energy is the energy needed to eject an electron from an atom. Compute the ionization energy of a hydrogen atom in its fourth
Carbon dioxide dissolves in water to form carbonic acid. Estimate the thermodynamic equilibrium constanst (K) for this reaction (delta Gf values: H2CO3= - 616.1, H2O= - 237.1, CO2= - 394.4) .
The reaction AB-> A+b is second order in AB and has a rate constant of 0.0245 M^-1 S^-1 at 25.0 degree celcuis . A reaction vessel initially contains 250.0 mL of 0.108 M AB which is allowed to react to form the gaseous product.
The label on an aerosol spray can contains a warning that the can should not be heated to over 130°F because of the danger of explosion due to the pressure increase as it is heated.
Why is acceptable to use a mixture of the alpha and beta anomers of D-(+)-mannose in this reaction? (i.e. why isn't it necessary to use either a pure alpha or the pure beta anomer
