Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths

MENTAL ILLNESS AND METABOLIC DISORDERS Name of Student Institution affiliation Abstract Objective of the study: To identify the relationship between low income mental patients‚ and metabolic disorders among the 235‚000 patients who have been diagnosed with mental health issues. The study did not target any specific mental health disorder i.e. it conducted a general study of the mentally ill patients in-order to be in a position whereby they could investigate the relationship.

Metabolic Syndrome: A Precursor of Heart Disease In 1988‚ Dr. Gerald Reaven was awarded the Banting Medal for Scientific Research by the American Diabetes Association and introduced the term Syndrome X to the medical community. According to Dr. Reaven‚ “Syndrome X is a simple way to refer to a cluster of changes that encourage the onset and development of heart disease.” (Reaven‚ 2000‚ pg. 40) The medical terms Syndrome X‚ Insulin Resistance (IR)‚ or Metabolic Syndrome (MetS) have been used interchangeably

What was the Bauhaus and what was its purpose? The Bauhaus was a school of art‚ architecture and design that existed in three German cities including Weimar‚ Dessau‚ and Berlin. The school was founded by Walter Gropius in 1919 and it lasted until 1933. During its time‚ Bauhaus went through different distinct periods under different directors and cities including expressionism‚ constructivism‚ functionalism and architecture. The Bauhaus was the start of modernism‚ at the same time‚ it changed the
