Reaction tests water splitting in photosynthesis‚ and can be observed when a color change occurs. This color change will occur when a molecule is split and electrons are removed from molecular oxygen and hydrogen ions. DCIP combined with sucrose or ethanol spinach mixtures‚ will give either a green color (indicating photosynthesis occurred) or no color at all (indicating no photosynthesis occurred)‚ depending on the factors and environments to which the mixtures will be tested.

causing hardships‚ increased food prices‚ and other problems. Ethanol has been blamed for the rise of food prices. Since corn is used for many different things such as food for us‚ ethanol gasoline and food for animals. Even though ethanol lowers our gas mileage corn is being used more for ethanol and making it more expensive for the people who would like to eat corn on a cob. In 2013‚ 40% of corn and other crops went to produce ethanol‚ 45% was used for feeding livestock and other animals‚ and only

This experiment aims to determine the dependence of its strength on both a changing current‚ and for a solenoid‚ changing number of turns and determine through linear regression the experimental value of permeability. Also‚ this experiment aims to tackle the similarity and difference between a magnetic field pattern produced by a solenoid and a bar magnet‚ as well as the difference between the field pattern of a NS-NS and NS-SN configuration‚ in which the former

Non-cardiogenic shock is caused by a circulatory collapse in the body that is not due to problems originating in the heart. Shock is commonly caused by hypo-perfusion though the blood vessels due to lack of blood in the vessels causing low blood pressure and rapid heartbeat. Besides cardiogenic shock‚ there are three other types that cause shock for non-cardiogenic reasons‚ obstructive shock‚ disruptive shock‚ and hypovolemic shock. Obstructive shock results from an obstruction that prevents blood

PERMEABILITY HOMEWORK Problem 1: Assume a vertical cylindrical core filled with water. The length of the core is 1 feet and its radius is 1/12 ft. Water density is 62.428 lb-mass/ft3 and water viscosity is 1 cp. We wish to inject additional water into the bottom of the core and flow water from bottom to top through the core where the top of the core is exposed to the atmosphere‚ i..e.‚ the pressure at the top of the core is 14.7 psi. What is the minimum pressure required at the bottom of the core

the mass and the given percent mass of ethanol‚ we found the density of pure ethanol for each known concentration of alcohol‚ and averaged the three calculated densities to give us a density of pure ethanol (0.8391 g/mL) that we could use to calculate the concentration of the unknown solution. We used this to calculate the volume of ethanol in the unknown test tube (7.918 mL)‚ and used the calculated density of ethanol to convert volume ethanol to mass ethanol in the unknown test tube (6.644 g).

Production was averaging one billion gallons per year in the early 1990s‚ grew to four billion gallons in 2005‚ and in 2007 exceeded six billion gallons (Renewable Fuels Association (RFA)). If current plans for new construction and expansion come to completion‚ production capacity will exceed

Distillation of an Ethanol- water Mixture Abstract The purpose of this experiment is to understand the process of distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol incollecting flask
