Describe the coordination geometry (e.g. octahedral) for each metal ion and the MX_nL_m formula for deoxy and oxy form of hemerythrin.
Calculate the average kinetic energies of the CH4 and N2 molecules at 286 K and 556 K?
Hydrogen exhibits several series of line spectra in different spectral regions. For example the Lyman series (nf = 1 in Balmer-Rydberg equation) occurs in the ultraviolet region while the Balmer (nf = 2) series occurs in the visible range
the specific heat of silver is 0.24 J/g degree celsius. how many joules of energy are needed to warm 4.37 g of silver from 25 degree celsius to 27.5 degree celsius?
63mL of a 1.70 M solution is diluted to a volume of 218 mL. A 109mL portion of the solution is diluted using 117mL of water. What is the final concentration?
The result described is impossible, given the fact that delta G is -60 kJ/mol. d. The activation energy for the reaction is very large; equilibrium has not been reached by 24 hours. e. An enzyme has shifted the equilibrium toward A.
The flask was then shaken until the solution was uniform. A 45.0 \rm mL sample of this glucose solution was diluted to 0.500 \rm L. How many grams of glucose are in 100. \rm mL of the final solution
Determine the pH of a solution of 10-3 M sodium formate. (Formate is a byproduct of microbial metabolism, and can also serve as an energy source for anaerobic bacteria.
A local FM radio rock station in San Antonio is known to operate at a frequency 99.5 MHz. Determine the energy associated with a mole of photons emitted by this station in J/mol. (106 Hz = 1 MHz) (1/s = 1 Hz).
Disregarding any other losses and treating the animal as a closed system, what was the change in internal energy of the animal?
The discovery of hafnium, element number 72, provided a controversial episode in chemistry. G. Urbain, a French chemist, claimed in 1911 to have isolated an element number 72 from a sample of rare earth (elements 58-71) compounds. However, Niels B..
