I was at the medical centre on Friday for my monthly check-up. After three long years‚ Im finally expecting another baby. It has been a long wait. Every month‚ my hopes were raised as high as a tsunami wave‚ but each time they crashed down on me‚ thirty-six times in all. I felt as if God was punishing me but I wished that He would punish me more severely in another way. One thousand days passed before a little seed grew inside me. A lady with a big belly came in after me. She took a clear plastic

Week 10: Oxidation and Reduction Reactions: The Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

students who facilitated the outreach. Their crispy laughter was evident of their enjoyment when we tour them to SM Iloilo and bought them snacks to ease their grumbling stomachs. Happiness is in the air- happiness was seen in their faces until the clock says our time is over and we need to return them to their respective parents. When we gave them gifts‚ their wide smiles and sparkling eyes was instilled in my mind because it was heart soothing seeing them that exalted. It was a tiring day activity

History of Clocks and the Impact of Electricity on them. Introduction: In this poster we are going to show you the history and the development of the clock through time and how it has impacted society. We will also show how electricity has affected the development and effectiveness of clocks. Sun clock: One of the first clocks on record is the sun clock. Sun clocks basically work on the principle that the position of a stationary object’s shadow will be in the same place at a certain

Symbolism Analysis: Gatsby’s Clock Have you ever wanted to turn back time and relive the past? In The Great Gatsby by F. Scott Fitzgerald‚ Fitzgerald tells a story of a man named Gatsby who was once poor and became wealthy in order to get Daisy‚ a girl who is a part of the “old money” society. He attempts to accomplish this goal by establishing a friendly relationship with Nick‚ who is Daisy’s cousin. Unfortunately‚ Gatsby’s goal of getting Daisy and reliving the past backfires and vanishes forever

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time
