1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the

the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This increases the heart rate because the movement of blood is faster than the resting heart rate. When performing a strength training exercise‚ the muscles contract allowing blood vessels to pass in and out. This builds the pressure in the body as well as increases the amount of

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

concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react

1. HOW IS UNEMPLOYMENT MEASURED? Based on my research (Abs.gov.au‚ 2015)‚ the Australian Labour Market Statistics (July 2014); the Australian Bureau of Statistics (ABS) measures the unemployment rate in Australia. The data came and it is published monthly from the Labour Force Survey (LFS) in Labour Force‚ Australia (cat. no. 6202.0). And are described by many attributes such as age; sex; marital status; geography; country of birth duration of job search. An individual is said to be employed if he

Internal Rate of Return In investment decision analysis you may need to calculate internal rate of return. “Internal rate of return (IRR) is the discount rate that gives the project a zero NPV” (McLaney‚ 2006). It is a good choice to use for investment projects. There is a formula for the internal rate of return: (A is the lower discount rate and B is the higher rate‚ a is the NPV at the lower rate and b is the NPV at the higher rate.) For example the Net Present Value (NPV) is 88 when the

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected

range. Both ranges carry a significant impact on one another and this is our attempt to show this‚ using factual findings. To begin‚ the specific territories are Modesto‚ California and Stockton‚ California‚ both of which are based in two different counties and neighbors one another. They both carry high crime rates; however‚ their economic stability is a huge factor in stabilizing the current crime rates and reducing the amount of heinous crimes that occur. Three main crimes that will be used to compare

Lab#: 15 Title: Exercise/pulse rate Aim: To investigate the effect of exercise on the pulse rate Materials/ Apparatus: Stop watch Diagram: Procedure: 1. The three middle fingers were placed just behind the bottom of the wrist as indicated in the diagram in order to see if the pulse could be felt. 2. (a) If the pulse was not felt the three fingers were moved about until it could be felt. (b) Changing the hand also helped to find the pulse. 3. The number of pulsation
