1a. Two reasons that the mass of the bag levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the

Family Health History Paper By: Allie Wade People all over the world usually have some kind of health issue in their family. Having a poor diet‚ not exercising enough and lifestyle choices are mainly what cause most of the health issues in America. Something else that plays a big part in health issues are genetics. My family‚ for example‚ has a history of several issues. Although my dad doesn’t have any health issues‚ his parents‚ my grandparents‚ both deal with type 2 diabetes and hypertension

Karmini Mondal Chemistry 245- 061 Biosynthesis of Ethanol from Sucrose Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g

Alcohol based fuels are used as alternatives to fuels that come entirely from non-renewable resources. The most common of these are ethanol and methanol. These two substances have a few similarities‚ but also significant differences. The similarities are so few that they can be listed concisely; just appearance and smell are similar for these two chemicals. If an individual were presented with samples of each of these chemicals‚ they would have to ignite it or consume it in order to tell the

KAAPA Ethanol‚ established in November of 2003‚ has created many new opportunities and jobs for the industry. Scott McPheeters and Shana Dahlgren gave an enthralling presentation of how ethanol system works and the benefits of the country’s adoption of ethanol and its byproducts. Video presentations were able to captivate the audience’s attention while it presented facts about the industry. McPheeters gave the delegates a trivia game to play that was filled with interesting information. He informed

Paraffin wax produces more energy per gram than Ethanol based on our test results‚ and simply by the molecule comparison itself. Since Ethanol is an oxygenated molecule and already contains oxygen‚ it cannot burn at the same intensity as Paraffin does‚ since Paraffin is
