USE OF SOCIAL MEDIA IN PROMOTING STAKEHOLDER RELATIONS IN THE EDUCATIONAL SECTOR DEFINITION OF SOCIAL MEDIA Social media has rapidly integrated itself into our everyday lives‚ both personal and professional‚ and it’s perhaps had no greater impact than on the world of marketing‚ with consumers and brands seeing enormous benefits and changes. Social media literally means interactive platforms through which individuals and communities create and share user-generated contents. Social media are social

4 revolutions and6 revolutions (maximum opening)and computed Reynolds number of 3823.79‚ 11659.14‚ 14733.30 and 21185.65 respectively. Based from the results‚ as the opening of the outflow valve increases the velocity of water increases with its volumetric flow rate and Reynolds number. Theoretically‚ the obtained trend is correct because velocity is directly proportional to Reynolds number. KEYWORDS: Reynolds number‚ laminar‚ turbulent INTRODUCTION: The type of flow occurring in a channel is important

about the experiment is that all the reagents used in this experiment wasn’t incorporated in the final product. This doesn’t abide by GCP # 2 atom economy because there was leftover unused solvent‚ and untitrated reaction mixture contained in the volumetric flask that was thrown away in the bio hazard asste bin. 3. One way the experiment could be made greener is to incorporate GCP # 1 (prevention)‚ because “it is better to prevent waste than to treat or clean up waste”. In regards to this‚ there was

Period 1 11/7/13 Chapter 35 Discussion Background: Potassium permanaganate is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ this is the equation: 8H+(aq) + Mno4-(aq) + 5e- Mn2+(aq) + 4H2O Since the KMnO4 – ion is violet and the Mn2+ ion is nearly colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing).

Method 1- Titration • For the titration‚ it is necessary to dilute the Sodium Hydroxide so that it is an easier concentration to titrate. Using a 25cm3 pipette‚ washed out with some of the NaOH solution‚ transfer 25cm3 of the solution to a 250 cm3 volumetric flask‚ and fill to the line with distilled water. The alkali will now have a concentration of 0.1 mol dm-3. • In the titration‚ the NaOH will be in the burette‚ and will be titrated into HCl in a conical flask: NaOH (aq) + HCl (aq) NaCl (aq)

Compleximetric Determination of Water Hardness Caindec‚ Patricia Ysabel B. Water hardness is a measure of the amount of calcium and magnesium carbonate dissolved as Ca 2+ and Mg 2+ in water. There are no health hazards associated with water hardness‚ however‚ it causes scaling‚ as well as forming of soap suds. Compleximetric titration is one of the best ways of measuring total water hardness using a standard ethylenediaminetetraacetic acid (EDTA) solution. EDTA solution is used as it has the

Lee Department of Biological Sciences‚ College of Science University of Santo Tomas‚ Manila‚ Philippines 1008 Date of Submission: February 17‚ 2011 Abstract In this experiment‚ the Winkler Method was used to measure the dissolved oxygen (d.o.) in a water sample from the pond in the Arch of the Centuries which had the owl statues. Then‚ the amount of oxygen is determined through a series of reaction. Usually‚ Winkler
