Liquid

On September 28th,2015 NASA researchers announced that they had discovered liquid water on the surface of Mars. They actually told news agencies that they had something big to discuss in relation to Mars. It took several space craft and several centers of research five years to come to this finding. Why is there such a push to find liquid water on mars? As far as science knows, life requires water. Rockets require hydrogen and oxygen. Humans require oxygen to breath and to function. If we want…

District Manager. These quotas have lead to associates even turning customers away to maintain high numbers. On one occation in my store, our General Manager would purchase packets of Liquid Armor, a liquid screen protector that is one of our metrics, on his own time to inflate the stores weekly sales of Liquid Armor. In addtion to using…

In this lab experiment, we will be using an unknown volatile liquid in order to understand the direct relationship between the molecular weight of a gas and its vapor density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to…

accurate melting point can be taken, leading to a more precise identification of a compound. The overarching goal was to isolate and identify three different unknowns in a given sample using these techniques. There are two types of extractions; solid-liquid extractions involve extracting a soluble compound from an insoluble (solid) material…

Fires involving gasoline are unique because they cannot be extinguished by water alone. “The ability of water without additives (foaming agents) to put out a fire is limited on low-flash-point flammable liquids” (Cote & Bugbee, 1988, p.168). The reason that water alone cannot be used on flammable liquid fires with low flash points is that the water will probably sink to the bottom of the fuel. If the fire was contained in a tank, the water would sink and cause the fuel to rise in the…

process and procedure for correction/adjustment and that all documentation and subsequent batch releases are issued to the work order for filling. This procedure will also eliminate accretion of previous blends in the liquid compounding area. 2.0 SCOPE: This procedure applies to the Liquid Compounding, Pre-weigh area and Lab. 3.0 RESPONSIBILITY: It is the responsibility of the Compounding Manager, Compounding Lead and Compounding associate, Scheduling Clerk, Pre-weigh Manager, Pre-weigh…

Recent revelations in the news over NASA finding “liquid” water on Mars has gotten many people excited about the possibility of sending humans to live on the planet, without much insight into the actual reasons why that idea is still not currently feasible. A planet must have much more than just water in order to be a habitable place, and these factors are often overlooked, in fact the same factors affecting the water supply on Mars are also the factors that factors behind the other reasons it…

for more accurate and reliable results to better answer the research question Liquid Evaporation This means that the quantity of nitric acid has decreased in some experiments and not in others, resulting in some experiment trials having more liquid than others thus causing changes in rates of reaction, reducing chances of experimental accuracy Maintaining the same conditions for all the tests and trials to prevent liquid evaporation causing faster/slower reaction rates Time of Reaction…

liquid children’s vitamins Liquid Childrens Vitamins are a great way to ensure your children get their nutritional supplementation on a daily basis. It is great for younger children who have difficulty swallowing pills or taking medicines. Instead of a hard gelatin capsule or an oversize oblong tablet. Liquid children’s vitamins is a great tasting liquid filled with all the vitamins, minerals that children need to stay well and grow up healthy and strong. Such basic things that children need,…

Kate Byrne DT299/4 CHEM 4128 Applied Physical & Analytical Chemistry Assignment Liquid Chromatography High Resolution Mass Spectrometry Hyphenated Techniques The term “hyphenated technique” was introduced by Hirschfeld in 1980. It refers to the combination of a chromatographic separation technique and a spectroscopic detection technique to form a new, more efficent instrument. The technique which will be discussed in this case is LC-MS. The aim of combining both techniques is to purify and…
