Make the assumption that N2 molecules are in a 3-D box that is 4.5 m long, 3.5 m wide, and 2.25 m high. Treat them as particles. If the temp is 25 C, calculate the average energy per molecule.
Assume n=nx=nx=nz and find the value of n.
Find the state that is next highest in energy and then determine the wavelength of a photon required to excite to that state.
How much heat (in kJ) is needed to convert 866 g of ice at -15 degress celsius to steam at 146 degrees Celsius? (The specific heats of ice and steam are 2.03 and 1.99 J/g x C respectively)
Calculate the molar concentration of OH - ions in an 1.37 M solution of hypobromite ion, BrO- (Kb = 4.0 10-6).
calculate the expected change in temperature for 4.5 g of nh4no3 dissolved in 100.0 ml of h20. assume that the
in the stratosphere chlorine atoms catalytically destroy ozone o3 producing the now infamous ozone hole above the
During an experiment, a student adds .339 g of calcium metal to 100.0 mL of 2.05 M HCl. The student observes a temperature increase of 11.0 °C for the solution. Assuming the solution\'s final volume is 100.0 mL,
Write lewis structure for these species, including all resonance forms, and show formal charges: CH2NO2- The formal charge of N=1 and the formal charge of O=-2.
It is estimated that about 0.02 m3 of pyrite (density 5 g/cm3) has "disappeared" from a rock face that is adjacent to a lake (original pH=6.7) with dimensions 100 m x 40 m x 10 m.
For the reaction NH4CL(aq)=NH3(g)+HCL(aq),delta g=58.8 kJ and delta h=86.4 kJ. Is this reaction favored. If so, how. What would be the entropy change for the reaction of 2.04 moles of NH4CL(aq) at 349K and 1 atm
At high temperatures phosgene (COCl2) decomposes to give carbon monoxide CO and Cl2. In a typical experiment, 0.631 g of COCl2 is injected into a flask of volume 472 cc. When equilibrium is established, it is found that the total pressure is 2.175..
A solution of 0.1% sodium dodycl sulfate (SDS) binds so strongly to polypetide chains that one detergent molecule is sufficient to saturate two amino acid residues.
It is possible to draw a valid Lewis structure that follows the octet rule for all of the following except one. Which one cannot be drawn without violating the octet rule
In air and according to Stokes Law, the settling rate of particles is proprotional to the squares of their diameters, if they have the same densities
