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

From January 30‚ 1933 to May 8‚ 1945 was The Holocaust; a period of desperation and misery for the Jewish population in Europe. This wasn’t a good time for Jews because a new chancellor was chosen for Germany‚ Adolf Hitler. Approximately 6 million Jews were murdered during this time; 1.5 million of them were children. These deaths added up to be about two-thirds of the Jewish population in Europe and one-third of all Jews in the world. This horrible attempt to eradicate the Jewish population

They influence us in terms of speech‚ sense of style and clothing‚ food we eat‚ the movies we watch and even how we think and decide. Our government does not give attention in our education‚ from colonial education to neo education means to maintain the control of U.S in our education. They want us learn based only on their books‚ they are making the young ones like robotic children “don’t ask

ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

wanted to portray the Jews as inhuman‚ inferior beings who were interested primarily in their own economic gain or in communism. All Jews and non-Aryans were excluded from Germany society. These are some examples of the acts of prejudice before the holocaust began. The Nazis introduced anti-Jewish laws‚ which gradually eliminated the rights of Jewish citizens. Jews were regularly persecuted and humiliated. All Jews had to wear a Yellow Star on their clothing. They could no longer hold government

When I look at this picture I don’t just see thousands of Jewish men and women being sent to the crematorium to be burned to death. I see the cloudy gloomy weather. It is such a depressing scene‚ imagine how they felt being marched to their death. You can help but wonder if some of the Nazis guarding them felt any sort of guilt as they were having all of these prisoners murdered right before their eyes or had their conscience grown silent from doing it so much. How their family’s felt when they what
