What is the difference between an open or closed distillation system? Is cooking an egg a physical or chemical process? Explain. Describe the steps that should be taken if 10 ml of ethanol in a 50 ml beaker ignites in the lab. Are separations of mixtures physical or chemical change...
How can the mixture of iron fillings and sulphur be separated? How would one describe pure substances and mixtures? Discuss how you would separate Fe+3 from Ca2+. What makes the following two mixtures different? Discuss with an example: 1. Homogeneous mixture. \\ ...
Some unusual properties of water are as follows: a. The peculiar properties of water in condensed form are due to the presence of extensive hydrogen bonding between water molecules. b. The abnormally high freezing point, boiling point, heat of vapour
the expansion of the Langmuir equation for binary mixtures by Markham and Benton is reproduced for liquid phase adsorption. Then, a kinetic approach for the mutual blocking of binding sites in mixtures is introduced to the Markham and Benton model. With it, an interaction parameter describing multi...

Toxicologists who study engineered nanomaterials and nanomedicines have been interested in both complex mixtures in environmentally- and physiologically-relevant conditions in order to decipher the role of physiochemical properties in induced mechanisms of toxic action. These analytical interrogations require mu...
Technical diving typically involves the use of specialized equipment such as twinsets, sidemount, closed circuit rebreathers (CCR), decompression, stage and/or bail-out cylinders, the addition of helium to breathing gasses, and utilizing a variety of gas mixtures over the course of a single dive...
Describe a method that can be used to separate each of the following mixtures metal a. Ag^+, Pb^2 + b. Mn^2 +, Fe^3 + c. Ni^2 +, Al^3 + d. Cu^2 +, Ni^2 + Precipitation calculations with Ni^2 + an Provide a general description of how electrometallurgy is used to ex...
