extract a metal Industrial mineral- either has some direct practical use‚ or take part in some industrial process Gems and precious stones are an exception to industrial metals as they do have a direct ‘practical’ application but are dealt with separately. Some common minerals include: * * Silica- (silicon dioxide) most common mineral on earth * Calcite- (calcium carbonate) main mineral in limestone and marble Ore: A naturally occurring solid material from which a metal or valuable

Experiment 1: Calorimetry Nadya Patrica E. Sauza‚ Jelica D. Estacio Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (∆T) was calculated by subtracting the initial temperature

the effect of concentration on the rate of a reaction Research question: To what extent does the concentration of hydrochloric acid affect the rate of the following reaction: 2 HCl(aq) + CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g) Data Collection and Processing: Table1: Different volumes of Co2 gas produced by Different concentrations of HCL acid. Volume of CO2gas formed from 5 different concentrations of HCL acid ±0.5ml 5 different concentrations of HCL acid (Mol) ±0.5ml Time (sec) ±0.1 0.25mol 0.50mol

then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL of Acetic Acid at 50% (10 mL per run). • Vernier Temperature Probe.

This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

Atausch July 28‚ 2014 Bio 102 Lab Final Exam: Acids and Enzymatic Reaction Purpose: To examine how an acidic fluid will modify the outcome of an enzymatic reaction. Introduction: Enzymes are “specialized proteins made by living cells that serve as biological catalysts.” (eScience Labs‚ LLC‚ 2013) These enzymes “allow certain industrial processes to be carried out at normal temperatures and pressures‚ thereby reducing the amount of energy and expensive equipment needed.”(BBC‚ 2012) Enzymatic

CASE STUDY US MAGNESIUM SEEKS PROTECTION In Feb 2004‚ US Magnesium‚ the sole surviving US producer of magnesium‚ a metal that is primarily used in the manufacture of certain automobile parts and aluminum cans‚ filed a petition with the US International Trade Commission (ITC) contending that a surge in imports had caused material damage to the US industry’s employment‚ sales‚ market share‚ and profitability. According to US Magnesium‚ Russian and Chinese producers had been selling the metal at prices

Effect of Temperature on Solubility of a Salt Ahmed Mohammed 17-nov-2013 Abstract In this experiment‚ you will study the effect of changing temperature on the amount of solutet will dissolve in a given amount of water. In this experiment‚ you will completely dissolve different quantities of potassium nitrate‚ KNO3‚ in the same volume of water at a high temperature. As each solution cools‚ you will monitor temperature using a computer-interfaced Temperature Probe and observe
