Determination is the ability to reach for something regardless of the difficulty. It comes with a strong desire‚ and persistence to achieve your goals. Prior to ninth grade I had no drive to become anything in life‚ I was just a leaf blowing into the wind. In school I had the lowest grades‚ in swimming I was one of the slowest people‚ . Through sheer determination I have risen to the top twenty-fifth percentile of my class‚ competed in State Championships for swimming‚ and I have been secretary and

Determination of the Concentration of Acetic Acid in Vinegar Lab Exercise 4 CHEM 1106 9/19/12 Purpose: Standardize a sodium hydroxide solution using a primary standard acid. Determine the molarity and the percent by mass of acetic acid in vinegar by titration with the standardized sodium hydroxide solution. Introduction: Vinegar is a dilute solution containing acetic acid. Since vinegar has a low pH‚ it can be titrated with a base. Titration is a method used in order to ascertain

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

considered as hard water. INTRODUCTION Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca 2+‚ Mg2+‚ Fe3+‚ SO42-‚ HCO3-. When this water evaporates or boils‚ the difficult to dissolve metal salts remain as a scaly residue. Hard water inhibits the effectiveness of soap and detergents. Calcium ions typically make the most significant contribution to water hardness. This is why hardness is measured in terms of mg CaCO3/L of solution. Hardness

Brain Death Determination When the brain has a lack of oxygen‚ even for a few minutes‚ it could lead to loss of brain functions such as a gradual loss level of consciousness or a complete loss of consciousness causing the person to slip into a coma. In the most profound cases‚ irreversible brain damage and death occurs. Oxygen deficiency can by caused by many things‚ such as; a brain injury‚ fall from height‚ traffic accidents‚ heart failure‚ stroke or some neurological disease. That may cause

Report of Density Determinations Density is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment‚ we will determine the mass and volume of each object and then we will calculate the ratio—the density. In the first part of the experiment‚ we should measure the density of some irregularly shaped chunks of rock. The Weight of rocks is 18.769g

INTRODUCTION In the diet of every nation‚ milk is considered as nature’s perfect food. The consumption of milk and its food products have been increased as a sign of prosperity. The growing underdeveloped countries in the last few decades have adopted milk and its food products in their diets. Milk can be defined as the fresh and clear lacteal secretion practically free from colostrums and obtained by the complete milking of one or more milky animals like cow‚ buffalo‚ goat etc. In human
