were reported for binary mixtures of N-methylformamide with O-substituted aniline (2-chloroaniline‚ 2-methylaniline and 2-methoxyaniline) over the entire composition range from 303.15 K to 318.15 K and at atmospheric pressure 0.1 MPa. These experimental data have been used to calculate excess volume (VE)‚ deviation in viscosity (∆η) and excess Gibbs energy of activation of viscous flow (G*E). The variations in these properties with composition for all the binary mixtures suggest that loss of dipolar

Background research Dry ice is a frozen mixture of Carbon dioxide‚ and like many other mixtures that give off Carbon dioxide dry ice is able to fill up a balloon. Using other substances that give off Carbon dioxide along with dry ice‚ which substances would be able to give off enough Carbon dioxide to inflate a balloon. The scientist will of course be controlling many variables. The scientists independent variable will be the substances they will be using‚ which is dry ice‚ yeast

Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed by adding 3 x 50 mL of 10% NaOH. The neutral component in CH2Cl2
