Experiment no. 1 Determination of moisture content (standard method - oven drying method) 1.0 Introduction Every type of soil has its own percentage of moisture content. The void in soil content water and air. The moisture content may varies for each types of soil. Different type of soil has different moisture content. Moisture content of soil also may be affected by the climate where the high humidity country tend to have higher moisture content in soil. Size or structure of the

Ice Calorimeter Determination with Mg June 18th 2013 Abstract: This experiment determines the amount of energy needed to melt ice. A spontaneous increase in enthalpy produce by combining 0.2036g Mg and 5.00mL H₂SO₄‚ ice was melted and readings were taken by using an ice calorimeter. Readings were taken before during and after the reaction were completed. The data taken shows a value of -405 KJ/mol while the theoretical value was -483.7 KJ/mol. Calculating the experimental

The years during the mid 1840s to 1850s in Ireland were definitely not the best for many families‚ it was a time of tragedy. These were the years during the horrific times called the Irish Famine‚ also known as the Potato Famine or Great Hunger. The Irish Famine claimed innumerable amount of lives‚ leading to a “mass emigration of famine survivors to the United States” (McCallum). There were countless of families who emigrated to America during this catastrophe in order to escape starvation‚ poverty

Marz Jhon V. Patricio QUANTITATIVE DETERMINATION OF THE ACIDITY OF SOFT DRINKS I. Introduction A. Principle Titration is a laboratory method that is the slow addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will

Water Shortage or Water Misuse The United States of America is known for her extreme overuse of everything. Americans see something they want and they simply take it. It was true when the young country pushed westward. The Native Americans were already there‚ but that mattered not; it was wanted‚ so it was taken. It is still true today. Americans as a people see what they want and they take it with very little regard to who had it first or where more might come from. Water is one of those

Europe. The second factor of overeating may be caused by boredom. Sometimes people eat because they have nothing to do. It is very easy to turn on the TV‚ take a lot of snacks‚ lie down on a couch and watch TV. That is why we have expression couch potato.

And last but not least‚ is very easy access to food than before. Just imagine how many opportunities

Title of the Experiment: determination of densities Introduction The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples‚ a unit volume means 1.0 ml. The units of density‚ therefore‚ are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter. Density is often used as a point of identification in the determination of an unknown substance. The density

CHEMISTRY DETERMINATION OF ENTHALPY CHANGE OF NEUTRALIZATION IA Criteria Assessed: DCP CE MS Introduction When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH- (aq)) from alkali‚ forming water. The identity of salt will depend on the nature of the acid and alkali used. H+(aq) + OH- (aq) → H2O(L) The combination of H+ and OH- ions in this way releases energy. In this practical‚ the
