Determine the molar internal energy (kJ/mol) of HCl (B = 10.59 cm-1 and ? = 2886 cm-1) under standard thermodynamic conditions. For the vibrational part, use N = nNa.
Why is the catalyst Copper Chloride faster at the decomposition of hydrogen peroxide than Postassium Iodide and Lead Oxide
Explain why the C=C stretching mode gives rise to a rather weak IR band in 1-methylcyclohexane
How does the entropy of the system PbI2(s) + H2O(l) change as PbI2(s) dissolves in water at 25°C?
Ammonia can be made by reacting calcium cyanamide (CaCN2) with water as shown: CaCN2 + 3 H2O => CaCO3 + 2 NH3. How many grams of calcium cyanamide are required to react with 417.8 g of water
The solubility of Ce(IO3)3 in a 0.20 M KIO3 is 4.4 multiplied by 10-8 mol/L. Calculate Ksp for Ce(IO3)3.
Reversible adiabatic processes are isentropic. Are isentropic processes necessarily reversible and adiabatic?
When a neon atom is electrified, the electrons jump to higher orbits. One of the electrons falls from an outside orbit to an inside orbit giving off red light with a wavelength of 7.34 x 10-7 m. Calculate the frequency of the red light given off b..
H2S (aq) is a polyprotic acid, meaning it can dissociate its hydrogen ion more than once. However, HS- (given its negative charge as well as its extra hydrogen ion) can act as either a base or an acid
Electron affinity can be defined for molecules just as it is defined for single atoms. Write a complete chemical equation representing the electron affinity of OH. Include all relevant state symbols ((s), (g), etc.)
2KClO3 + heat > 2KCl + 3O2, How many moles of O2 form as 3.0 mol of KClO3 are totally consumed.
Although the aluminum cylinder is a solid (and, therefore, is quite in-compressible), it actually contains quite a bit of empty space.
what will be the concentration of dichlobenil in the pond? The following conversion factors will be helpful: 1 acre=43,560ft2 1ft=12in 1in=2.54cm 1cm3=1mL 1ft3=28,317cm3
