Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

ON THE RATE OF REACTION Aim To study the effect that temperature and concentration of iodide ion solution have on the rate of iodide ion I⁻ oxidation by peroxodisulphate ion S₂O₈⁻‚ creating an iodine clock reaction. Introduction I decided to choose as the topic for my investigation the rate of reaction for its vital importance in the human body. Indeed I am really interested in Biology and especially physiology and I would like to study medicine. The rate at which different reactions happens in the

INDIGENOUS PEOPLE REACTION PAPER WOW! After the symposium‚ I realized how lucky I am to be in a concrete house‚ not worrying if the strong wind will take it with all its might; to live in a more comfortable house with comfortable clothes on. Indigenous people’s always stressing the hell out of them searching for food everyday‚ they can’t even apply for a stable job here in the city or at least away from secluded areas where they live. On the other hand‚ I salute them for they’re always active

The movie took off with Steve Jobs talking in a melodramatic way to the audience‚ it seems but as the angle of the scene shifts‚ it was shown that he was actually talking to a director and that they were currently in the middle of shooting a commercial which is for the Apple Computer. The scene then changes showing

SIGNOS Reaction Paper Global warming is one of the most serious hazard that we our facing today. The alarming signs were seen‚ even here in our country. Drought happens during rainy season while typhoons come upon summer months. The abnormal rainfall causes the rise of sea water level and more areas experience flooding. These are only some of the signs of growing global phenomenon. This environmental crisis brings risk to a million lives. Signos is one of a documentary that will awaken our minds

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

The movie itself started out slow‚ I have noticed that with a lot of older movies like this one‚ it took a while for me to catch on to the point of the movie‚ or to figure out what it was about. Slowly the movie started picking up and it began to make more sense to me. There are a lot of characters that I had to write down on a piece of paper because
