from the material list and set up my data table. I combined the zinc and HCl‚ then captured the Hydrogen that was produced and observed the combustion reaction with a flame. I then captured more hydrogen to use later in the experiment. I combined manganese with hydrogen peroxide which bubbled much the same as the zinc and HCl to produce oxygen. I observed the reaction of the oxygen with a burning ember. I then captured more oxygen in the bulb with the hydrogen‚ and observed itʼs reaction of extinguishing

Manganese‚ such as hard manganese‚ pyrolusite‚ rhodochrosite are weakly magnetic‚ commonly used in magnetic separation recovery. ’ Ilmenite‚ wolframite‚ monazite (phosphorus cerium lanthanum mine)‚ niobium-tantalum minerals are weakly magnetic minerals.

BRIGGS RAUSCHER OSCILLATING CLOCK COURSEWORK Aim: To investigate the effect of temperature on the rate of reaction. To investigate the order of reaction with respect to hydrogen peroxide and ethanoic acid (acetic acid) by the use of an oscillating clock reaction. To determine the activation enthalpy with and without catalytic ions and use this to compare the effectiveness. To investigate the rate equation‚ rate constant and possible mechanism for this reaction. Background research: The Briggs-Rauscher

Modified Winkler Method for Dissolved Oxygen Determination Tiffany T. Lee Department of Biological Sciences‚ College of Science University of Santo Tomas‚ Manila‚ Philippines 1008 Date of Submission: February 17‚ 2011 Abstract In this experiment‚ the Winkler Method was used to measure the dissolved oxygen (d.o.) in a water sample from the pond in the Arch of the Centuries which had the owl statues. Then‚ the amount of oxygen is determined through a series of reaction. Usually‚ Winkler

In 1996‚ the Ethyl Corporation filed a $250 million claim against Canada under Chapter 11 regarding a gasoline additive they produced called MMT. Background • Methylcyclopentadienyl manganese tricarbonyl (MMT) MMT is an octane-improving fuel additive. The chemical compound was developed in the 1950s by what became the Ethyl Corporation (today part of the Afton Chemical Corporation‚ but hereinafter referred to as “Ethyl”).[ii] MMT

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
