According to the given data propylamine (CH3CH2CH2NH2) boils at 49 degrees C, Trimethylamine [(CH3)3N] boils at 3 degrees C;trimethylamine has reasonably high solubility in water Propylamine is entirely miscible with water; considering that isobu..
Historically, the solid residue that is left after the Dichloromethane -or methylene chloride (CH2Cl2 )solution is evaporated has a lower melting point that its literature value, due to impurities.
A student studied the clock reaction described in this experiment. She set up a reaction mixture by mixing 10mL of 0.010 M KI, 10mL of 0.0010 M Na2S2O3, 20mL of 0.040 M KBrO3 and 10 mL of 0.10 M HCL.
An equilibrium mixture at 225 degrees C contains 0.10 M NH3 and 0.20 M H2 for the reaction 3H2 (g) + N2 (g) --- 2NH3(g) If the Kc at this temperature is 1.7 X 10 2.
