For this experiment I am investigating how the light intensity as my limiting factor will have in impact on the amount to oxygen produced‚ to should the rate of photosynthesis.Therefore‚ all the controlled variables must remain constant‚ if not there could be an affect on the accuracy of the dependent variable. The CO2 levels are the same for each trial because before placing the sodium hydrogen carbonate i will weigh it with a measuring scale for 1.5 grams. After completing the five measurements

How does acid precipitation affect marble and limestone buildings? Acid rain is a type of precipitation that is characterised by containing contaminating substances such as sulphuric and nitric acid‚ both of which have harmful effects on the environment. Both marble and limestone are extremely vulnerable to the damages done by acid rain due to their components. These materials contain calcite‚ a substance that easily reacts and dissolves with acid. Acid rain is the cause of the destruction of many

Do Ads Affect Obesity ’s Rate? Name: Nejoom Taher GGU ID: 0571638 Applied Critical Thinking Research Paragraph Instructor: Natalie Barbera Summer 2013 Abstract Obesity rates have been increasing in the recent years which makes people concern about the reasons of it. Despite the fact‚ that many studies indicate there is no direct correlation between obesity and advertising‚ people continue to believe that

a time when we are no longer young as we used to be before‚ but in fact we will start to age as the years go by. This can affect how we react to certain things and how quickly we respond. People who are older have nerve impulses that react more slowly and will have a slower reaction time than people who are younger. I think that as we grow older our reaction time does decrease.

determine how the 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

Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration of STS

Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is

the substances used in respiration (sugar or oxygen) and the waste products created. The breakdown of glucose also releases carbon atoms‚ which become available for biosynthetic reactions‚ enabling the yeast to grow and reproduce by budding or fission. The rest of the carbon ends up in the by-products of these reactions‚ such as carbon dioxide‚ ethanol‚ and other more minor
