Colorado Northwestern Community College Science of Biology Mrs. Farrow Lab 3 – Slime Time Submitted by Chase Kenemer 22 February 2015 Abstract Polar solvents dissolve‚ or pick-up‚ polar substances and non-polar solvents dissolve‚ or pick-up‚ non-polar substances. In the conducted experiment‚ the polarity of molecules and their properties are explored. The results of using two solvents on both polar and non-polar inks‚ further verify this to be true. The student conducted the experiment

Experiment 1: Purification of Benzoic Acid by Recrystallization III. Introduction Purification - physical separation of impurities and by-products from an impure sample pure substance. *Distillation- for liquid compounds‚ *Recrystallization- solid compounds Recrystallization - precipitation of a solid cpd. from a saturated solution in the form of crystals through cooling or evaporation -7 steps: 1) selecting the appropriate solvent 2) dissolving the solute 3) decolorizing the

What is water purification? Water purification generally means freeing water from any kind of impurity it contains‚ such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some

purify water. After straining the water twice through clean muslin cloth‚ it is boiled for ten minutes lo kill the microbes present in it and also remove the temporary hardness of water. Filtration - Different varieties of filters are used to purify the water at domestic level. Filter rods can be installed. These rods are made of china porcelain and it is porous and hollow from the centre. When water is put through it‚ it is purifies and drips in out clean into a small tank‚ ready for use. Industrial:

discrete time linear time invariant (LTI) systems. Further‚ it introduces Z-transform and its inverse and followed by their applications to the analysis of LTI systems. A framework for designing analog and digital filters (both FIR and IIR) is introduced starting with mapping of filter specifications from continuous Laplace transformation to Z-transform‚ structure realization based on Direct‚ Cascade‚ and Parallel forms‚ analysis of finite precision effects‚ and ultimately implementation and testing

Steve Patterson. In this Photoshop text effects tutorial‚ we’re going to learn how to create a fire text effect‚ engulfing our letters in burning hot flames. We’ll be using Photoshop’s powerful Liquify filter for most of the work on the flames themselves‚ but we’ll also be taking a look at the Wind filter‚ using adjustment layers to colorize the flames‚ layer styles for adding color to our text‚ layer masks for blending the flames with the letters‚ and more! Here’s the result we’ll be working towards:

Well‚ when your homes own water pressure pushes the water through the membrane‚ and subsequent sediment and carbon filters‚ the impurities are simply filtered out once again and flushed down your drain. All you’re left with is delicious‚ clean‚ crisp tasting drinking water. To gain this result‚ many RO systems‚ including our own‚ adopt a 4-5 stage filtration process and
