Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

Introduction: A balanced chemical equation has reactants and product that has to represent a formulae. The amount of each element‚ number needs to be the same in either side of the equation. (E.g.‚ HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(g)‚ this is the equation given for this lab). This help us view the study of Law of Conservation of Mass‚ when either side of equation is equally balanced. The calculation for formula mass helps determine if you need to convert grams to a particular

Exploring adolescent physical activity in the UK Introduction. The current recommended physical activity guidelines for younger people to maintain a healthy lifestyle and improve health is at least 60 minutes of moderate‚ to vigorous intensity activity per day. This should include aerobic activity‚ and muscle and bone strengthening activities. In order to gain additional health benefits and well-being Amounts of physical activity greater than 60 minutes is required. (National Health Department 2012

Sport and physical activity is a major thing in the lives of many people in Australia. The people in Australia intend to spend more of their time on leisure than their work. Involvement in sports or physical activity mainly depends on two factors. The two factors are personal factors and socio cultural factors. Personal factors are those that factors that are unique to a particular person and directly affect that person’s regular capacity to be involved in sport and physical activity. The socio

Physical Activity AHA Scientific Position Physical inactivity is a major risk factor for developing coronary artery disease. Coronary artery disease is characterized by deposits of fatty substances‚ cholesterol‚ calcium and other substances in the inner lining of arteries that supply blood to the heart muscle. It also contributes to other risk factors‚ including obesity‚ high blood pressure‚ high triglycerides‚ a low level of HDL ("good") cholesterol and diabetes. Even moderately intense physical

Research Question: How will an increase of FeSO4 concentration affect the activity of the enzyme catalase? Hypothesis: By increasing the concentration of FeSO4‚ there will be a decrease in the activity of the enzyme catalase because the Iron (ii) in the metallic ion will act as an inhibitor during the catalysis of the hydrogen peroxide into O2 and H2O. Introduction: We rely on oxygen to provide us with energy (ATP) and go through all the phases of aerobic respiration. However‚ oxygen can be
