CHAPTER 1 INTRODUCTION A. Background of the Study Concentration has been defined as the ability to direct one’s thinking in whatever direction one would intend. Concentration plays vital roles in doing well in studies. A student has to work really hard and concentrate firmly to get concepts well in mind. All students have the ability to concentrate some of the time. But at other times students’ thoughts are scattered‚ and their minds race from one thing to another. They don’t have the ability to

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

Evaluation Like any experiment‚ there were a number of potential errors during the procedure of the experiment. Errors could have arisen as a result of the uncertainties associated with the instruments I used to take measurements‚ and also as a result of errors associated with the actual method. Of course‚ due to the limitations of the procedure‚ they could not be eliminated completely‚ so I will explain what I did to reduce them to an acceptable level and how I could have improved my method to

discuss how concentration ratios are used to determine total market shares within four specific industries. I will also discuss the levels of competition within those industries and how oligopolies can benefit society. Case‚ Fare‚ and Oster defines concentration ratio as the share of industry output in sales or employment accounted for by the top firms (2009). They are used to measure the total output produced by a certain number of firms within an industry. Four-firm concentration ratios

Summary of Findings 1. Music affects the growth of Mung beans. As established in the experiment and based on the data gathered‚ music has a great effect on the growth of Mung beans. The varying degree of effect is dependent on the type or tempo of music to be played. 2. In general‚ music helps in the growth of plants. It hastens the growth of plants. As we conducted and observed our experiment‚ we noticed that classical music helps the Mung beans’ growth. Plants exposed to rock music grew slower

Economic growth is the overall growth in an economy. Gross National Product and Gross Domestic Product are the normal measures of economic growth. Because growth can come in many ways‚ GNP and GDP are not particularly good measures. More so‚ economic growth can occur from having more people in an economy. If economic growth occurs more slowly than the population growth‚ then there can be economic growth‚ but the average person is less well-off. As economic growth is measured as the annual percent
