The energy required to break a single carbon-carbon bond is 348 kJ/mol. Calculate the minimum wavelength of light needed to break the C-C bond. Could UV lamps be used to break the C-C bond?
For the reaction CH4+202=2H2O+CO2, calculate the percent yield of carbon dioxide if 1000. g of methane react with excess oxygen to produce 2300. g of carbon dioxide.
Calculate the percent yield for the reaction: P4 (s) + 6 Cl2 (g) → 4 PCl3 (l) if 75.0 g of phosphorus reacts with excess chlorine gas to produce 111.0 g of phosphorus trichloride.
If 69.5 kJ of heat is applied to a 1040. g block of metal, the temperature of the metal increases by 11.4°C. Calculate the specific heat capacity of the metal in J/g°C.
Calculate the solubility of BaSO4 in (1) pure water, (2) 0.0125 M BaCl2, and (3) 0.0125 M KCl. What effect do BaCl2 and KCL have on the solubility of BaSO4?
Calculate the equilibrium constant Kp for synthesis of HCl at 298 H2+Cl2------>2HCl
Molecular formula of C10H14. The carbon NMR shows 7 carbon peaks and 4 H peaks. H(4) broad multiplet at 7.0, H(3) singlet at 1.4, H(1) multiplet at 1.2, and H(6) doublet at 1.0. Has strong UV absorbance at 260nm
Imidazole, acting as a nucleophile, catalyzes the hydrolysis of phenyl acetate by attach on the carbonyl carbon atom of the ester. The imidazole displaces the phenoxide anion and forms acetyl imidazole
A 5.0 L bulb filled with 175 torr of He and a 7.5 mL bulb filled with 325 torr of Kr are connected together allowing the gases to mix. What is the final pressure in the combined bulbs, assuming the gases behave ideally and the volume of the connec..
