It is clear that salt‚ also known as sodium chloride‚ should no longer be used on our roads in the winter months. The first two reasons why salt needs to stop being used are because salt negatively affects aquatic ecosystems and causes damage to vegetation. The third reason is because thankfully‚ there are alternatives that we can use‚ that would be benefiting us which we should use instead of sodium chloride. To begin with‚ sodium chloride is detrimental to our aquatic ecosystems when it is

This experiment was all about observing a chemical reaction. During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum was added into the Copper Chloride was turquoise. As we added the Aluminum the color changed to green and the water boiled. So we met the purpose of this lab. Purpose: The purpose

You know the original mass of the beaker. You also know the mass of the beaker plus the product you produced‚ which is zinc chloride. The difference between these two masses is the mass of zinc chlorine

Then‚ put a mixture of sodium chloride dissolved in distilled water and the dissolved alloy back into the fume hood to heat for 15 minutes on the hot plate. 5. Filter the Silver Chloride • Take the mixture from the fume hood and pour onto the filter paper in the funnel and drain the liquid

Sodium chloride is table salt that is commonly used in the food industries as a flavor enhancer and preservative society. Sodium chloride is also used in glass production in society. Salt helps lower the melting points of ice or snow‚ therefore they are used in cold climates to help get rid of accumulating snow or ice. Sodium chloride is normally made by evaporating the sea water. Sodium chloride is a metal halide‚ which is made up of 40% of sodium‚

added. If one teaspoon of ammonium chloride‚ calcium chloride‚ and sodium chloride are added to separate glasses of water‚ then ammonium chloride will keep the water cold the longest because it is most commonly used in brand name cold packs. In order to test the hypothesis‚ the scientists will label four cups to keep track of what chemical will go in each cup. One will just be plain water‚ while the next will be labeled ammonium chloride‚ calcium chloride‚ etc. Then the scientists will pour fifty

Introduction: Copper (II) Chloride is the compound with a chemical formula of CuCl2. This is a light brown solid‚ which slowly absorbs moisture to form a blue green dihydrate. Copper (II) Chloride is highly soluble in water and will produce a blue solution. solutioAluminum is the compound that has a chemical formula of Al. This is a silver solid that can be easily formed‚ machined‚ or cast. In this lab‚ we will be finding the limiting reactant between Copper(II) Chloride and Aluminum. The limiting
