Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

What Factors Affect the Labor Market? Adrienne Rudy ECON 210 Professor Kenneth Tirpack February 14‚ 2015 As a professional recruiter‚ I would prefer a candidate with a college degree. Even if the degree obtained does not exactly align with the position I am looking to fill‚ a college degree can give me a lot of information about an applicant. One of the most important thing that a college degree tells me is that the person is a hard worker. It takes drive‚ hard work‚ and dedication to obtain

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

oxygen released for the cold trial was 38 mL‚ 11 mL less than the control. Conclusion: The hot trial produced the most oxygen of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

The aim of this experiment was to show the water potentials of young‚ old and damaged potatoes and different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn
