THE EFFECT OF CONCENTRATION ON REACTION RATE INTRODUCTION • Concentration is one factor which has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium

Heat Loss The aim of this practical is to find to what extent does the surface area to volume ratio of an object affect the rate of heat loss from the object Hypothesis: As the ratio of surface area to volume of an object decreases the rate of heat loss from the object will also decrease. Objects with the same surface area to volume ratios loose heat at the same rate so long as there are not other variables involved. Background Knowledge: The surface area to volume ratio of an object

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

311: Deliver a Presentation 1. Understand the purpose of preparing for and evaluating a presentation. 1.1 Different types of presentation can be used to provide a range of different information. The different types can be used to inform‚ instruct‚ persuade or to facilitate decision making. Presentations have various formats depending on what is supposed to be achieved. Different types of equipment also provide different information and may facilitate different styles of learning such as using a

Appex Corporation Under the leadership of Shikhar Ghosh‚ Appex Corporation has undergone several significant structural changes in order to cater to its rapid growth in the past three years. Each of these structural changes just generally improved the operating performance of Appex Corporation for a short period of time‚ ultimately each different structure has generated a new set of barriers and problems that constrained the innovation‚ performance and growth of the company. Based on the changes

This case study is focused on a company called Vigor Skin Care. Initially known as the “sleeping dog‚” Vigor was barely raking in a profit during its initial years of development. However four years ago‚ Peter Markles‚ the current head of Vigor‚ accepted the challenge of reviving the company. Markles first step in solving this problem was forming a team whose members were committed towards achieving a common goal; bringing success to Vigor. In addition to Markles‚ Sandy Fryda‚ Vigor’s marketing director

Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

Marble Chip Investigation Method 1.Set up the equipment as diagram shows. The measuring cylinder must be filled with water and then inverted into the tub. 2.Measure the quantity of hydrochloric acid and marble chips to the decided amount. Add water to the acid to change the concentration to what you need. 3.Take note of the amount of water in the measuring cylinder. 4.Put the marble chips and hydrochloric acid into the conical flask. Replace the bung and start the stopwatch. 5.Once the decided

and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white‚ green‚ red‚ blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis‚ oxygen‚ a product of photosynthesis‚ replaced the bicarbonate solution‚ made the disks less dense and rise to the top. The rate of photosynthesis

trust among the plant and ultimately motivated everyone to work to a Level 3 CI assessment in 2008. As for the Team 4-Ward plan‚ I do not believe I would go through with it yet at the Williamsport plant. I feel that the plant has achieved a lot up until this point and am not sure if they are ready to jump into a different type of situation which will require many changes too their standard functions. Though I think it has the potential to work in the Williamsport plant‚ I do not feel it would
