≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the

Adopt a Single Rate Flat Tax System The one topic that has continually been a major topic in the United States is the topic of taxes. It has been a key component of political campaigns at all levels since the political scene has been of interest to me. There are two major tax systems that are viable options in the U.S. today. There is the federal individual income tax system and a single rate flat tax system. The U.S. currently uses the federal individual income tax system. This type of

Accounting rate of return Accounting rate of return (also known as simple rate of return) is the ratio of estimated accounting profit of a project to the average investment made in the project. ARR is used in investment appraisal. Formula Accounting Rate of Return is calculated using the following formula: ARR = Average Accounting Profit Average Investment Average accounting profit is the arithmetic mean of accounting income expected to be earned during each year of the project’s life time

Define the Problem: The real national unemployment rate is higher than the U.S. Department of Labor’s December figure shows. When the underemployed and discouraged are added to the unemployment numbers‚ the national unemployed rate rises to 16.6%. This causes morale to be low and Americans seem to be giving up. Variables Identified by Order of Influence: 1. The government no longer counts people as unemployed when they stop looking for work. The unemployment numbers don’t account for part-time

Unit 3. Assignment 1: Bacterial Growth Rates 1. Mediums that could be used to determine shigellosis include Btilliant Green Agar‚ and Triple Sugar-Iron Agar. Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with

Homeostasis and how the body responds to exercise. This report will interpret the results of the practical activities that was done in order to monitor the changes in heart rate‚ temperature and blood pressure before and after exercise. Blood pressure is the measure of how much pressure is put on the walls of the blood vessels when the blood is pumped through them. This is measured in two parts‚ the larger number on top is known as the systolic pressure‚ this measures the pressure as the blood

CheckPoint Crime Reporting and Rates Response What is the purpose of the major crime – reporting programs? What makes a successful crime reporting program in the U.S.? The purpose of major crime – reporting programs is to keep track to see if crime is decreasing or increasing in the various communities. Also to keep track of the heaviest crime stricken areas to determine if police patrol needs to be increased. Also to keep track of which crime is being committed the most in the various communities

Design Aspect 1: Defining the problem and selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise
