1.49‚ 1.325‚ and 1.34 g/mL. These values areincorrect because the density should not have been over 1.0 g/mL. This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing plate majorly affects the values read. For instance

Energy Refuge‚ written by Ethan K.‚ is an informative article about the important role that ethanol is bringing into the automotive industry and claims that it is a sustainable source of energy for our vehicles to use. He develops this claim by talking about how ethanol would work‚ and why it can be more beneficial than oil production for vehicles. Ethan’s purpose is to bring to everyone’s attention that there are alternative products

the hydrogen peroxide. Denatured enzymes are enzymes whose shape has been altered and are no longer active (Wiggins). Ethanol is able to denature enzymes and caused the enzymes in the potato piece to be unable to function. This caused the ethanol-soaked potato to have less activity than the water-soaked potato since it did not have its enzymes denaturized like the one soaked in ethanol.

A developed country does have a moral duty to produce food over fuel crops when hunger is global issue. Allowing someone to go hungry to be able to fuel a vehicle is immoral. There is a moral duty to make sure that America is not consuming all our food sources to lessen the cost of our fuel imports. Food should be in demand and be available for the poor. It is important to be able to curve the hunger with a source that has many options for usage. Farmers grow corn to feed their animals‚ family

of the Pigmentation of an Onion Cell within 40% Ethanol and Deionized Water Purpose: To measure the amount of pigment in a solution of 40% ethanol and deionized water both containing pieces of an onion with a spectrometer. Hypothesis: 40% ethanol breaks down the cell creating less surface area and spreading out the pigment while the deionized water absorbs the pigment in a greater surface area. Procedure: Add 10ml of deionized water and 40% ethanol to a 6-dram vial Add 6g of chopped onion to the
