It is important to use de-ionized water in this experiment because you don’t want the electrolytes in the water to affect the aqueous solutions conduct an electric current, especially if it can’t.…
In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with.…
1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame…
1. What safety equipment is available to you while you do your experiments? How far are they from you while you are conducting your experiments? This includes fire extinguishers, phones, showers, etc.…
Johnny is 12 years old and is currently learning about atoms in his science class. He recently decided to adventure outside and see if what he was learning could be put to the test. Now, it was spring and the slugs were starting to take over Johnny’s mother’s garden. Before he could go outside and play his mother asked him to go spread salt across the slugs in order to save her flowers. Johnny grabbed the salt and headed out to the garden ready to get rid of the slugs. As he walked over to the garden Johnny noticed the words sodium chloride on the side of his salt container.…
I would advise my friends to read the instructions one more time. 175F* seems to be fairly low in cooking flan. Chances are that he probably mixed up Celsius with Fahrenheit.…

The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound, and compare them for cost effectiveness, safety and potential yield of the compound.…
In the winter, salt is spread daily on the driveway in order to melt snow and ice. In the spring, when the grass begins to grow, it is noticed that there is not any grass growing about 3 inches from the driveway. In addition, the grass appears to be growing slower about 1 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 by temperature. Salt that is commonly used for deicing is rock salt also known as halite. Rock salt’s crystals are much larger than the common table salt’s crystals ("What is salt?," 2013).…
A. Based on your observations make an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too.…
Sodium attracts water. Sodium chloride is table salt. Too much dietary salt raises blood pressure and aggravates hypertension. Diets rarely lack sodium.…
The chemical components that make up salt are the fused elements of sodium and chloride (Editorial Board, 2012). If there is abundance or very little salts present in dissolve fluids, there could be interference with routine cell functions. Plants depend on water for fluids within the living cells. Too much salt disrupts the flow of the necessary fluids to get to the roots. In addition, a disruption of the photosynthesis process which depends on water particles to carry oxygen and hydrogen atoms throughout the plant becomes stagnant. The salt, mixed with snow and ice, melts down to a watery substance that contains high levels of sodium chloride.…
Sodium is an abundant metallic element which is an important mineral for all living organisms. It is also widely used industrially to make an assortment of consumer goods. In a pure form, sodium is a soft, silvery gray, highly reactive metal. Pure sodium is usually stored in a nonreactive substance, as it oxidizes rapidly when exposed to air, quickly forming a thick coating. The soft metal appears in an abundance of compounds, such as sodium chloride, better known as salt. It also exists in high concentrations in seawater, and it is among the 10 most abundant minerals in the Earth's crust. The chemical element of sodium is also highly explosive when exposed to moisture and water. It is the major positive ion in fluid outside of cells. Na+, the chemical notation for sodium is a reference to a Latin word natrium, used to refer to a specific type of salt. Sodium's atomic number is 11, placing it among other…
