ARM SPAN ACTIVITY SHEET. 1. Take turns measuring the height (in inches) and arm span (in inches) of each group. member. Record the data in the table. 2. Choose 6 of your classmateâs data points and record them in your chart. Make sure. you decide with your group members which data points you are choosing to ensure.
The non-random two-liquid model (short NRTL equation) is an activity coefficient model that correlates the activity coefficients of a compound i with its mole fractions in the liquid phase concerned. It is frequently applied in the field of chemical engineering to calculate phase equilibria.
Isopropyl Î²-D-1-thiogalactopyranoside (IPTG) is a molecular biology reagent.This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.or induction, a sterile, filtered 1 M solution of IPTG is typically added by 1:1000 dilution into a logarithmically growing bacterial culture, however, different final concentration of IPTG may also be used.
