This movie has begun in Princeton University on September 1947. It starts with a class of guys listening to a professor on how each of the guys in the class was awarded a scholar ship to study in Princeton. Then there comes a guy name John Nash, who is the main character in this movie. From this, it will tell a story about John Nash and will also talk about his disorders in this movie. The group of guys that where in the class are now outside and talking to each other and getting to know with…
the equation landing position of the ball thrown by the robotic arm stand. We must create the equations in terms of the radius, height, arm rotation speed, and release angle. The equations must be made with those variables because, those variables are what can change where the ball will land in the cup, and will make the equation more useful to the client. To make sure the equation will remain accurate we have to keep track of all the units throughout the process. Knowing that all equations…
points in Desmos, (2 toppings, 13.85) and (4 toppings, 16.99), both are medium pizzas. I asked students to get the price per topping which is the slope and subtract it two times from $13.85 to get the base price or the y-intercept. We tested the equation by opening the website of pizza hut. Students are able to compare the prices as well as qualities of the pizza stores. In this activity I was able to engage students in exploring real-world issues and solving authentic problems using digital…
Chemical kinetics are governed by the mathematics of systems of differential equations (Thermodynamics and Kinetics). This means that the rate of any chemical reaction is determined by the type, and amount, of reactants present. Note the rate of a reaction is how fast it occurs. Furthermore, such rate equations can either be distinctively linear or non-linear when graphed. Non-linear equations are supposedly more complex as they generally react to small changes within its parameters…
CHML 1046 General Chemistry 2 Laboratory Experiment “The Rate Law of an Iodine Clock Reaction” Objectives: To apply method of initial rates for investigation of influence of concentrations of reactants on the rate of the reaction. Determine the rate law of a particular reaction experimentally. Observe the effect of catalyst on the reaction rate. Examine the influence of temperature on the rate of this reaction. Calculate activation energy for the reaction from rate constants at two…
The reaction between sodium thiosulphate and hydrochloric acid forms the word / chemical equation below: sodium thiosulphate + hydrochloric acid -> sulfur dioxide + sulfur + water + sodium chloride Na2S2O3 (aq) + 2HCl (aq) -> SO2(aq) + S(s) + H2O(l) + 2NaCl (aq) When sodium thiosulphate reacts with diluted hydrochloric acid, a mixture of…
This report gives an information which is related to the reaction between acidified potassium iodide and hydrogen peroxide. Before calculating the rate of this reaction, the reaction will be carried out 3 times and values will be got. A special timer will be used to measure the time. It could be expected and argued that each time will be able differ from the others in each reaction and it can be explained by changing the quantity of hydrogen peroxide. At the final, it will be obviously observed…
reactant molecule, which is referred as unimolecular step. Also there may be a single collision between two molecules, which is referred as a bimolecular step. It should be noted that majority of the reactions that are written as a single reaction equation actually consists of a series of elementary steps or process. The main objectives for the study of chemical kinetics are: (a) To analyze the sequence of elementary steps giving rise…
arguments that not only try to show the existence of life, but also the existence of communicative civilisations. Frank Drake formulated the Drake equation one of the most famous one of these models. Rather than evaluate and quantify the number of civilisations, the equation yearned to inspire scientific dialogue at SETI ( Search for Intelligent life). The equation shows that the number of civilisations - N - is a product of certain variables such as the number of Sun like stars older…
Experiment 4: Kinetics of Nucleophilic Substitutions 1. Determine the effect of varying [OH-] on the rate of the reaction. To do this, you should complete the following table: Experiment [tBuCl]0 (M) [OH-]0 (M) Time (s) Reaction rate (M/s) Rate constant (s-1) 1 0.03 0.003 65 4.89 · 10-5 1.62 · 10-3 2 0.03 0.006 213 3.15 · 10-5 1.05 · 10-3 3 0.03 0.009 362 2.96 · 10-5 9.85 · 10-4 What is the dependence of [OH-] on the rate law? The effect of the increased or…
