Liquid crystal display

One of the most unusual substances in chemistry, slime blurs the line between solid and liquid stages of matter. Slime and other substances like it are common in the average everyday life today, and yet are almost unnoticed. Slime is a colloid, a substance that shares both liquid and solid traits. Many colloids are polymers, which are a certain type of molecule. Although slime may seem simple, in reality it is quite complex in the microscopic standpoint. Slime can also be referred to as a…

them steep for 7 - 10 minutes with a watch glass on the top and the heat on low. Excessive heat can decompose caffeine so do not let the tea dry out. 2. Squeeze the tea bag against the side of the beaker with a stir rod to remove as much of the liquid as possible. Let the solution cool to room temperature. 3. Pour the tea into the separatory funnel. (Make sure that the stopcock is closed). Add about 10 to 20 ml of methylene chloride and shake gently. Vigorous shaking will lead to an…

Oxygen can be delivered by low or high flow systems depending upon the client’s need. Low flow methods allow for room air to be inhaled along with the supplemental oxygen; examples of low flow methods include nasal cannulas, face masks, oxygen tents, and transtracheal catheters. The nasal cannula can deliver 2 to 6 L/minute and is the cheapest most commonly utilized device tolerated well by clients. In addition, the device is easily applied and does not block the mouth allowing the client the…

Steel pressure tanks are very strong as they were designed to withstand a great amount of internal pressure. Because of this, it is not unusual to find that many of the larger, steel pressure tanks have been converted into unique structures or repurposed for other uses. Some of the larger steel pressure tanks have been converted into unusual, multilevel round houses. Some of these houses are elevated, while others are ground level or subterranean. Steel pressure tanks have also been adopted…

In the “ If the earth has layers than the top layer is the least dense.” the hypothesis was accepted. Data that supports this is that canister number one had the least amount of sand and a density of 0.40g/mL3.This canister was the least dense of the three canisters. This is why it floated on the surface of the water. Opposed to canisters numbers two with more sand than canister number two and canister number three had the most sand .Water’s density is 1 g/mL3 . The reason canister one floated…

Does a Measurement Result in a True Value? Limitations of Measurements Elizabeth Lechtholz-Zey & Marisa Loredo 10/5/15 CHEM 101-08 Purpose To determine the differences in precision and accuracy in weighing 10 mL of water using a 50 mL beaker, a 10 mL graduated cylinder, and a 50 mL buret. Data Temperature of water: 23.0ºC 100 mL beaker weight: 50.557 g # of additions of water to the 100 mL beaker * 50 mL beaker (±5 mL) * 10 mL graduated cylinder (±0.05 mL) * 50 mL buret…

means that only a small amount of crystals were recovered. This error could be due to the fact that some of the organic compounds may have formed hydrogen bonds and therefore been soluble in water resulting in the loss of some organic compound during filtration. Another reason for such a low percent recovery could be due to the drying agent. If the drying agent is added in large amounts it could lead to losing of the organic solvent by adsorption of the organic liquid. A better experimental…

Policy considerations Fluid replacement Most patients with diabetes insipidus (DI) can drink enough fluids to replace the loss of urine. When oral intake is insufficient walhaybrnatrmia accessible and replace losses with dextrose and water or intravenous (IV) fluid that is the mattress does not cause asmoli with regard to the patient's serum. Not sterile water without dextrose intravenously, because it can cause hemolysis. To avoid high blood sugar, and excessive size, excessive rapid…

In addition, procedure part H contains the viewing of cheek cells, cheek cells are a high-caliber option for identifying the membrane, and cytoplasm of a cell. To begin, place a drop of methylene blue on a slide, then smear a toothpick amongst the inside of the cheek, lastly smear the toothpick onto the stained slide. Cheek cells just like starch cells are hard to be viewed without the addition of a staining chemical, in this case, the methylene blue will make the cheek cells have a slight blue…
