Low-density lipoprotein

of the eggs is greater than the density of water. Then salt water 1-2 a spoon and stir in the eggs slowly, still also sank because of the eggs is still greater than the density of water. Drift An object that is dipped into the liquid will float if heavy objects are similar in style to the top or the object in equilibrium By the time the water was given a 2 ½ spoon of salt and stir gradually then egg will be on a State of drift. This happens because the density of water is equal to the mass…

Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and liquid…

while the pretzel and control group continued to drop. I think this trend is explainable because those who drank liquid voided more liquid. In the second graph there is no distinct trend. In all but the control group the flow rate started relatively low and increased over time, the control group started incredibly high (36.52 mL/min) and dropped rapidly. The third graph looks at total dissolved solids in the urine. In all but the water group the TDS dropped slightly and then rose again, but in…

this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the percentage recoveries were pretty low, all somewhere around 20 %. The only high percentage recovery was that of the neutral compound. This probably happened because the remaining solid that wasn’t dissolved with the acid, phenol, and amine like it should…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

to push it up causing it to float; the less density of the boat the nearer to the surface the vessel floats. The boat…

three questions in regards to density. The first question inquired which method of density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end. In the first half of the experiment, the density of copper is calculated…

Objective- Our goal for this lab was to calculate the Density of a substance. We needed to make sure we had the materials to find mass and volume and then use a formula to calculate density. Introduction- The main principle of this experiment was to figure out the Density of certain objectives given to us in the lab. We had to know the the formula D-M/V in order to find the density of that object.We also needed to know the density of water(1.0 g/l) in order to predict if something would float…

Simple distillation was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water.…

Experiment 1 Density By Jessica Schmidt Chem 112L-S23- Athukoralage Gunawardana September 20, 2016 Erin Whitehouse The first part of the experiment consisted of finding the accuracy and precision of three different measuring devices, a 50mL beaker, a 25mL graduated cylinder and a 25mL pipette. The mean volumes and uncertainties were found to be 22.5mL 1.9, 23.72 .25, and 24.89 .43, respectfully. The 25mL pipette was found to be the most accurate out of the three. The density of water was…
