CUP OF LAVA Camille Sager Darielle Donato Eric Valerio I. Introduction Salt‚ also known as common salt‚ table salt‚ rock salt‚ or halite‚ is an ionic compound with the formula NaCl (sodium+chloride). Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. Because of its importance to survival‚ salt has often

The labels fell off two bottles each containing a colourless solution‚ one of which was sodium carbonate solution and the other was sodium chloride solution. The addition of which solution to a sample from each bottle would most readily enable the bottles to be correctly relabelled?

foot from the driveway. Prior to an experiment being conducted‚ it must be determined what the salt compound being applied to the driveway is made up of in order to get a clear picture of how it may be affecting the grass growth. Salt is sodium chloride that occurs naturally on earth as mineral halite. When mineral halite evaporates‚ it turns into salt lakes. The chemical compound is NaCl with 60.663% elemental chlorine (Cl) and 39.337% sodium (Na). Salt crystals are cubic in form and can be modified

In our search for prosperity‚ growth and success‚ we are destroying the system that we as human are completely dependent upon. Population growth‚ water-intensive agriculture and economic development are using water faster than it can be replenished. Our Earth is a place where beauty exists‚ a place where 6.6 billion people and 15 million other species live‚ a place filled with 1.4 cubic kilometers of water. Although 70% of the planet’s surface is blanketed with deep oceans water‚ freshwater only

Report Introduction Mummification is an ancient Egyptian method which is a natural or deliberate process intended to dehydrate the body to preserve it. They done this because they believed that if a body was left to rot then it would destroy their soul‚ so they believed that the body needed to be intact to serve as host for the soul. So they preserved bodies so they could use them in the afterlife‚ where the Egyptians believed they would make a journey to another life. To start to mummify a body

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane (methylene chloride)‚ trichloromethane (chloroform)‚ pentane‚ hexane‚ petroleum ether are some of the solvents commonly used for extracting aqueous solutions. Petroleum ether and ligroin are mixtures of hydrocarbons whereas the other liquids mentioned earlier are pure
