Consider this reaction, which occurs in the atmosphere and contributes to photochemical smog:
C(s) + O2(g) →CO2(g)
If there is 10.65 g C and excess O2 present, the reaction yields 31.3 g CO2. Calculate the percent yield for the reaction.
Show that the equilibrium bond distance between the molecules is given by ro = 2^(1/6)*σ and that the bond energy (the value of the energy, E, at ro) is given by -?. (Binding energy is negative. i.e., energy decreases compared to when the components ..
A current of 10.0 amps flows for 2.00 hours through an electolytic cell containing a molten salt of mental X. This results in the decomposition of 0.250 mole of metal X at the cathode. The oxidation state of X in the molten salt
2 no g o2nbsp--gt 2 no2nbspga sample of air at a certain temperature is contaminated with 2.0ppm of no by volume. the
Compute the Gibbs free-energy change of the above reaction as it takes place in mitochondria at pH 7 and 25°C. Explain the concentration of reactants and products are [NADH]=2 mM, [NAD+]=1 mM, and PO2= 0.05 atm.
Excess air for combustion is calculated using the assumption of complete reaction whether or not a reaction takes place. For the typical combustion process the products are CO2 gas and H2O vapor. In combustion processes, since any oxygen in the coal ..
