5.5 Candy Chromatography Background Information: Paper Chromatography is a separation tool in which pigment is put on a paper made of cellulose and water‚ and placed in a solvent‚ in this case isopropyl alcohol. Due to capillary action‚ the solvent crawls up the paper‚ separating the pigments. This technique is used to identify components of a mixture‚ even unknown ones‚ and can be used to isolate components into pure samples. Real world uses of this technique includes identifying certain biomolecules

viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids have different viscosities. Factors‚ which affect viscosity of a liquid‚ are: Size of a molecule:

examine 2 different types of liquid body armour. Liquid body armour is protective clothing with liquid chemicals designed to strengthen it to absorb and/or deflect slashing‚ stabbing and penetrating attacks by weapons. The poster will discuss two different liquid used to strengthen kevlar (modern armour material). The first is a colloid of silicon dioxide particles suspended in polyethylene oxide. this liquid is a Shear thickening fluid which hardens on impact. the second liquid used is a magnetorheological

Part I: Density of Unknown Liquid Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1: Empty graduated cylinder is 25.5 subtracted from 36.5 of the liquid and the cylinder combined equals 11 grams of liquid. Trial 2: 36 grams of water and liquid combined minus the 25.5 of the empty cylinder means equals 10.5 grams of liquid only. Trial 3: Again 36 grams of liquid and the empty cylinder minus

mixture that would be Solid/Liquid would be Skim milk. Although skim milk contains mostly water it also contains casein‚ which is a small protein. The casein protein is so small it may not be thought to be a heterogeneous mixture‚ but if the skim milk curdles the mixture can be separated. A Solid/Liquid solution could be Seawater. The seawater is homogeneous which makes it a solution. The mixture of oil and vinegar to make a vinaigrette salad dressing is a Liquid/Liquid heterogeneous mixture. Due

form of acyclic alcohol is ethanol which is a clear‚ volatile‚ flammable liquid that boils at 78.4℃. It is used as an industrial solvent‚ car fuel‚ and as raw materials in the chemical industry. Ethanol is widely used as a solvent for human contact or consumption‚ including perfumes‚ flavorings‚ colorings‚ and medicines. Another type of acyclic acid is methanol‚ and it is also the simplest sort of alcohol. It is a clear liquid that resembles ethanol is odor and properties‚ but it has a slightly lower

measure volume‚ mass‚ density‚ and specific gravity of solids and liquids with accuracy. Equipment: Students use the electronic balance to measure the mass of metals‚ pipettes‚ and pipettes holding liquids. The user presses the tare button to set the scale back to 0 g‚ and then places the metal or pipette onto the balance. The result is rounded to two decimal places. The graduated cylinder is used for measuring volume of a liquid or water displaced by a solid. The students look at lines‚ at eye

Sound A. What is the definition of Sound? Sound is everything that a person‚ animal or computer can hear. It can be created in a countless number of ways and occurs from anything as simple as tapping on a table. All sounds are a series of vibrations that travel through a medium in all possible directions. The cause of sound is the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics:
