Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃ + Weighing Bottle (in grams) 3.62g±0

Purpose: The main purpose of this experiment is to standardize a solution of EDTA by titration against a standard solution made from calcium carbonate‚ CaCO3. Procedure: A 50-mL buret‚ a 250-mL volumetric flask‚ and 25- and 50-mL pipets were obtained from stockroom. The 0.5 g of calcium carbonate was weighted in a small 50-mL beaker. Approximately 0.4 g of the carbonate was transferred to a 250-mL beaker. 25 mL of distilled water was poured to the large beaker and 40 drops of 6 M HCl were added. Then

grinding mill which is widely used in the calcium carbonate grinding process. Firstly‚ the calcium carbonate ore be put into the primary crushing equipment jaw crusher to crush‚ then to the secondary crusher to get the size which is suitable to grinding in the T130X superfine grinding mill‚ after these crushing and grinding processes‚ we can get the suitable size finished production or the calcium carbonate powder. We also provide the whole calcium carbonate grinding production line machines‚ jaw crusher

Egg shell as face powder (related literature) Eggshells are composed of around 95% calcium carbonate‚ a mineral that is very important for industry‚ nutrition and agriculture. There are many studies trying to find new ways to utilize this resource and their natural absorbent properties‚ as in treating cadmium in wastewater. So‚ never toss out those egg shells. They’re not garbage‚ but can be very useful around the house and yard. They also help to save you money by replacing many expensive‚ toxic

Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken

Usually‚ this part of the egg is thrown away after the eggwhite and yolk are taken from it and used. Although‚ there are some who used eggshells as ornaments‚ they are few‚ and this practice is not common. Study shows that the eggshell contains calcium carbonate - a form of limestone that can be converted to chalk – that material that we use in writing on the blackboards. The purpose of this research is to produce a chalk that is non-toxic and therefore safe for school children‚ teachers‚ and other

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and to test for contaminates such as NaCl and KCl. These tests helps us to determine the properties
