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…
as the R² value is 0.9697. The hypothesis that the reaction would be first order was also supported, which can be seen in graph 2 of the results, where the natural log of the molarity was plotted against time and the trendline was linear, with the equation of ln(M) = 0.0016t + 0.1434. This is because…
CFO Tool 3 & 4 Whoever you are, and whatever income or debt you have, I think it is important to try to think of yourself like a business entity. Like a business you will have income and expenses. A balance sheet and an income statement tell a business what they are worth, defines income and spending, and also helps the firm set and measure goals. Both of these tools are useful for long term planning. A business is often measured by profits, and your budget is the same way. Since the…
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…
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…
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…
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…
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…
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…
