Draw the major isomer of 4-methylbenzaldehyde and benzyltriphenyl phosphonium chloride at room temperature mixed with NaOH
That a supercooled gas eventually phase separates is consistent with the 2nd Law of Thermodynamics because the phase separation lowers the Helmholtz free energy of the system
Calculate the heat capacity of a calorimeter if the combustion of 4.660 g of benzoic acid led to an increase in temperature of 7.148 degree celsius.
Calculate the equilibrium concentrations of I2, Cl2, and ICl. (Kc = 0.110 at this temperature.)
Question- An X-ray beam with a wavelength of 171 pm diffracted off a crystal at an angle of 23.8. What is the value of the spacing between the planes of atoms in the crystal that gave rise to this diffraction
Question- 2NO2(g)+F2(g)?2NO2F(g) is first order in NO2 and first order in F2. If the concentration of NO2 was increased by half and the concentration of F2 was quadrupled, by what factor would the reaction rate increase
In addition polymerization of methyl methacrylate, the benzoyl peroxide is an initiator. Why is benzoyl peroxide called an initiator and not a catalyst
