Dolomite mining is vital for business. Dolomite is type of carbonate mineral which incorporates iron dolomite and manganese dolomite. Dolomite may be the major mineral part made up of dolomite and dolomite limestone. The dolomite may be used in building elements‚ porcelain‚ glass and refractory after dolomite crushing. In chemical field small crusher‚ agriculture‚ environmental security‚ energy conservation‚ and so on. Therefore‚ the dolomite crusher is broadly used. The dolomite is especially utilizable

Writing Exercise – FePO4 Polymorphs 1. Compare and contrast the crystal structures and crystal chemistry of quartz‚ α-FePO4 and β-FePO4. FePO4 is a quartz-type of iron phosphate. It is different from other α-quartz isotypes due to the fact that the A-cation is a transition metal. The low-temperature α-phase can be from 294k neutron powder diffraction to high-temperature β-phase 1073K. As the quartz start to transit at 980K‚ from α-β‚ the Fe-O-P bridging angles start to increase value and the tetrahedral

Purpose: To observe the reactions of specific aqueous solutions with specific aqueous reagents. Introduction: A solution is as a homogeneous mixture containing two or more substances. Reagents are added to solutions to create a chemical reaction or added to see if anything occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example‚ iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the presence

Beanium Investigation The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons‚ but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles‚ we made our hypothesis the following:

Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction

BERYLLIUM Beryllium is a hard and brittle alkaline earth metal‚ which is greyish in colour‚ and an excellent thermal and electrical conductor. The melting point of beryllium is 1278°C‚ the boiling point is 2970°C. There is a fine layer of beryllium oxide covering it’s surface so it will not react with water or steam. However‚ it will react with oxygen when heated to around 600°C. Beryllium originally named glucinium‚ which derives from the Greek word “glykys”‚ which means sweet. This

Mini-Report: How Do Scientists Report Data? “Determination of the Empirical Formula of an Unknown Lead Oxide” By: Dr. C. Steven Joiner In this paper‚ they walk through and explain the process known as smelting. The experiment demonstrates the historical process known as smelting and could theoretically be used to determine the empirical formula of other metal oxides found in nature. This paper explains how the process of smelting and how metals can be extracted from their ores. This is because

a ratio of the moles of those elements. “Empirical” also means “experimentally determined”. In this experiment‚ we find the empirical formula of the oxide of magnesium. We will accomplish this task by reacting a massed amount of magnesium with the oxygen in the air. Knowing the original mass of magnesium and the final mass of the magnesium oxide‚ you can find the mass of the oxide portion. From these two masses‚ you can find the empirical formula‚ the ratio of moles. Procedures: 1. Obtain a
