Does anyone know what the reactivity order is when the alkyl halides undergo hydrolysis by the sn1 mechanisms and sn2 mechanism?
Describe how you would prepare the following aqueous solution: 230 g of a solution that is 0.60 molal Na2CO3 starting with the solid solute.
The enthalpy and entropy values are listed beneath each substance: 2 A + B ? 3 C + D ? Hf (kJ/mole) - 200 -50 -18 - 25 ? s (J/moleK) 25 40 300 75
A reaction at 1.83 atm produces 11.9 L of a gas and evolves 91.3 kJ of heat (exothermic). Calculate the change in internal energy of the system (in kJ).
