The way CDs work is basic but complicated at the same time. The plastic cover on the CD is to help prevent the aluminum from getting scratched and ruined. The plastic is also the main base of the CD itself. The plastic base or the CD is about 0.047in or 1.2 mm thick. It usually has 2 layers on it for the body and the protective layer. The DVD player reads on 1 and 0 it is a way the computers work too but this time on a CD. If they were to stretch the 1 and 0 out it would reach about 3 miles if not

Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must

So we’ve talked about what makes the DEWALT DG5204 so tough‚ but what makes them so comfortable? Firstly‚ the layered gel padding that surrounds the knee adds support and protection. The thick padding means they stay comfortable no matter what position you may find yourself in while working on flooring. The gel padding contours to your knee so you don’t get that feeling of having something digging into your knees‚ which is a common complaint among less well designed knee pads. The straps are a slip-buckle

Why Is Calcium Chloride Powder Used Extensively As A Bleaching Agent? In simple terms‚ calcium chloride is an inorganic compound having chemical formula CaCl2 (H2O)x where x can be 0‚1‚2‚4 and 6. All the salts produced by calcium chloride powder has a unique characteristic that they are highly soluble in water. This helps in applications where you need to remove snow‚ ice‚ or frost from any surface or even simple dust removal. It can absorb moisture from the surrounding environment‚ which is also

Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

why not? HI isn’t an ionic compound. It is a covalent compound because both hydrogen and iodine are nonmetals. 6) Why would the bulb light up when placed in an aqueous solution of sodium chloride but not in a solid sample of sodium chloride? In a solid sample of sodium chloride‚ sodium and chloride are bonded together ionic and so there aren’t any free electrons to support the flow of electricity. When sodium

Synthesis of t-Pentyl Chloride Introduction: Using SN1 reaction mechanism with hydrochloric acid‚ t-Pentyl alcohol was converted to t-Pentyl chloride in an acid catalyzed reaction. The reaction took place in a separatory funnel designed to separate immiscible liquids. The crude product was extracted by transferring a solute from one solvent to another. The process of washing the solutions by phase transfer was used in order to remove impurities from the main solvent layer. Finally‚ the crude
