Experiment 7 INVESTIGATING STOICHIOMETRY WITH SODIUM SALTS OF CARBONIC ACID Introduction In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and

Compounded with natural rubber and styrene- butadiene in the production of automotive tires. The process for creating styrene-butadiene rubber was through an emulsion procedure that used polymerization as the means of producing a material that had a low reaction viscosity‚ yet had all the attributes of natural rubber. The butadiene industry originated in the years leading up to World War II. Many of the belligerent

Low Calorie Diet Versus Low Carbohydrate‚ What is the Difference? Comm/155 05/12/13 Sandra Davis Being overweight and obese has become an increasingly alarming problem in this country. In 2007 the Center for Disease Control stated that between 1980 and 2004 obesity prevalence doubled among adults‚ and over 34 percent of all American adults were overweight or obese in 2006. Obesity is known to cause an increased risk of many diseases‚ such as heart disease‚ high blood pressure‚ diabetes‚ and

1. Provide the aim and background information 2.1. Diffusion is the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and

An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in

LCCs (Low Cost Carriers) first emerged in 1950‚ by the Pacific South Airlines started offering nothing but low prices on air travel. Followed by the great success of Southwest Airlines from 1967 onwards‚ as well as facilitated by the liberalisation in air transport market‚ it has been in centre stage of the global civil aviation industry ever since. In spite of facing many challenges such as high oil prices‚ softening demand‚ surplus capacity‚ new participants as well as subsidiaries from FCCs (Full

The Low Fares Airline---Ryanair By Kuan Li Introduction: Chief executive Michael O ’Leary blamed weaker exchange rates‚ greater competition and the continued impact of austerity measures in Europe for decline. However‚ sources at other airlines queried Ryanair ’s statement‚ saying they had yet to see similar signs (Thomas‚ 2013).In other words‚ that means the environmental impact of Ryanair is less than other airlines. At the same time also can know that Ryanair has strong actual strength. The

Gracen Seiler April 7th‚ 2015 Section- 109 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction- This experiment is intended to help find a better understanding of chemical stoichiometry through titrations of NaHCO3 and NA2CO3 with HCl. A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form in a nuclear reaction. Titration is when a measured amount of
