Multiple regression‚ a time-honored technique going back to Pearson’s 1908 use of it‚ is employed to account for (predict) the variance in an interval dependent‚ based on linear combinations of interval‚ dichotomous‚ or dummy independent variables. Multiple regression can establish that a set of independent variables explains a proportion of the variance in a dependent variable at a significant level (through a significance test of R2)‚ and can establish the relative predictive importance

SIMPLE DISTILLATION OF VODKA (ANTONOV) Kristel Joy M. Tan‚ Joshua Michael L. Torres‚ Pauleen Anne S. Vanadero‚ Paulene Arielle P. Ynzon and Rachel Pauline E. Zaballero Group 10‚ 2D Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is the most common technique‚ it is a process wherein the liquid is separated from the solution by boiling the liquid solution and condensing the vapor in order to get the distillate. There are four kind of distillation: simple distillation

Experiment 1: Simple Distillation and Boiling Points- Separation of Liquids February 24‚ 2014 Analysis In this experiment‚ the distillation of three groups of two miscible liquids was performed. First‚ Ethanol and 2-Propanol were distilled. The boiling points of ethanol and 2-propanol had a difference of 5°C. The percent recovery for both ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient

Procedure: The addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate
