An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

that are linked by common carbonate or bicarbonate technology. This was quite helpful for the company at the beginning but as the time passed by, the growth of 15% annually started to become static which raised concern at the higher management devising a new strategy to steer company out of the looming crisis. To give an overview of whole situation, sales became stagnant as company’s strategy was to sell products which are extensions to baking soda i.e. sodium carbonate. To bring in a change, for

ENVIRONMENTAL SCIENCE YEAR: FIRST YEAR EXPERIMENT NO. : A.1.1.3. T.A.: BRIGHT KOFI LEONARD DATE: 7TH NOVEMBER, 2007. Aims and Objectives: 1. To describe water hardness.

Chemistry Coursework – Rates of Reaction Investigation Introduction In this investigation I am going to be investigating the reaction between marble chips and hydrochloric acid, and to see what differences in the rate of this reaction arise when different concentrations of acid are used. Below is the word equation for this reaction: Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water Below is the fully balanced chemical equation for this reaction. CaCo3 +

Introduction The purpose of this project was to demonstrate the effects of ocean acidification and temperature increase on shellfish. Ever since the Industrial Revolution began, carbon dioxide emission in the air has greatly increased, and around the same time, the temperature of the ocean, along with the atmosphere, showed a similar trend. Scientists claimd that ocean acidification and temperature increase is deadly to marine life, including shellfish. It was hypothesized that the mass of the shells

Calcium effects humans’ everyday in many different ways. It has chemical effects on humans as well as it impacts people's health. Both are very important for our own day to day lives. These aspects will be touched on in this report. Chemical Calcium is an alkaline earth metal that is too reactive to be found isolated in nature (Dobberpuhl 2004). It is the third element of group 2 on the periodic table. Its atomic mass is 40.075 and its atomic number is 20 (Calcium 2000). The name calcium originated

rows A through E: cobalt (II) nitrate, copper (II) nitrate, iron (III) nitrate, barium nitrate, and nickel (II) nitrate. Afterward, two drops of each of sodium phosphate, sodium iodide, sodium sulfate, sodium chloride, sodium bicarbonate, sodium carbonate and sodium hydroxide were added to the five vertical wells under columns

In this lab experiment, an unknown metal carbonate went through a chemical reaction with 1.0 M barium chloride, forming products of barium carbonate and an alkali metal chloride. The unknown alkali metal carbonate also went through a chemical reaction with 1 M hydrochloric acid, forming an alkali metal chloride, with liquid water, and carbon dioxide gas as products. A final flame test was done to reveal what the unknown alkali metal was. Once all molar masses were calculated, the masses were extremely

reaction characteristics of basic copper carbonate 〖mCuCO〗_3⋅n〖Cu(OH)〗_2 were observed by changing the reaction mole ratio. The reaction mole ratio of sodium carbonate to copper chloride (II) was controlled from 1.08 to 1.68. Fig. 1 shows the XRD patterns of copper carbonate powder. At a reaction ratio of 1.08, paratacamite (Cu_2 Cl(OH)_3 ), beside alkali copper carbonate, was formed because of incomplete reaction at a copper content of 53.9 wt%. Lack of sodium carbonate may cause incomplete reaction with

hard water sample, while a low concentration is soft.4 Water hardness is important in that it can cause many problems. The equation below shows how calcium can create problems. “Calcium bicarbonate → Calcium carbonate + Water + Carbon dioxide Ca(HCO3)2 → CaCO3 + H2O + CO2”3 Calcium carbonate, also known as scale,is sometimes referred to as “one of the banes of industry”4. The formation of scale blocks pipes and tubes4 and is the culprit behind the hated bathtub rings.3 To fix these problems, it
