The team is currently working on a web-based program to help students understand the key features of the periodic table and information to guide students to help the teaching and understanding of the use of titrations. You have to produce word documents or powerpoint presentations that will provide the information for the web-based software. Remember: During this (and other assignments) credit cannot be given for a diagram  copied from the internet unless, (1) It is referenced and (2) You have interpreted the diagram in some way, for example, added your own labels or further described the concept conveyed in the diagram. Task 1 – Chemical Bonding and the Periodic Table In this task you have to describe atomic structure, outline the key features of the periodic table and describe chemical bonding Draw a diagram of a Calcium atom, label the key components of the atom. P1i The periodic table contains over 100 different elements in a specific order. Describe how the atoms in the periodic table are arranged. You will need to make reference to (a) groups, (b) periods, (c) metals and non-metals, (d) solids/liquids/gases. Choose three different elements and explain why each is in a particular group / period P1ii Ionic, covalent and hydrogen are the three main types of chemical bonding. Draw a series of diagrams, with explanations to outline the process involved in each type. P1iii Task 2 – Volumetric Analysis This task will require you to make a ‘Standard Solution’, this is a solution of known strength. You will make a solution of sodium carbonate. The strength of sodium carbonate (Na2CO3) is usually measured in moles. A one molar (1M) solution means one mole of substance (solute) per litre of solution. A mole is the molecular mass of a substance in grams. To calculate the molecular mass, the atomic masses of all the atoms in the molecule need to be added together. For example, the sodium carbonate molecule consists of one atom each of sodium (Na), carbon (C), and oxygen (O). Their respective atomic weights are: Na 23,C 12 and O 16, so the molecular weight, is 23 + 23+ 12 + 16 + 16 + 16 = 106. Thus 106 grams of Na2CO3 equals one mole of Na2CO3, and a 1 molar solution of Na2CO3will contain 106 grams of Na2CO3chemical, per litre of water. Using all the safety measures required, make a ‘Standard Solution’ of sodium carbonate. It can be any strength you like (within reason!) but you must know the strength exactly. This part of the task will be assessed by the teacher. P2i You will now use your standard solution to calculate the strength of a sample of HCl (Hydrochloric Acid). Procedure†¦ 1. Rinse all equipment with distilled water 2. Using a pipette add 25 cm3 of Na2CO3 to a conical flask 3. Add 3 or 4 drops of phenolphthalein. The solution will turn pink. 4. Fill the burette with Hydrochloric acid. 5. Add acid to the alkali, note how much acid is needed to neutralise the sodium carbonate, the solution will turn clear (to the nearest 1cm3) 6. Repeat the experiment a further three times, this time being accurate to 0.1 cm3 7. Take the average of the acid needed (from the three experiments in the previous step). P2ii Calculate the strength of the acid using the following information†¦ Na2CO3 + HCl ïÆ'   NaHCO3 + NaCl At equilibrium: Moles of Na2CO3 = Moles of HCl (as they react in a 1:1 ratio) Molarity of HCl (moles per litre) x Volume of HCl (litres) = Molarity of Na2CO3 (moles per litre) x Volume of Na2CO3 (litres) Molarity of HCl (moles per litre) = Molarity of Na2CO3 (moles per litre) x Volume of Na2CO3 (litres or ml) Volume of HCl (litres or ml) P2iii M1i Task 3 – Further Calculations This task requires you to further understand and describe the molecular changes from the previous experiment. The experiment reacted Na2CO3 with HCl to make NaCl and H2O. 1. Explain what makes HCl an acid/ 2. Explain what makes Na2CO3 an alkali, when dissolved in water? The diagram of Sodium carbonate may help you to explain this 3. Why does the hydrogen (H) form a positive ion in a hydrochloric acid solution? 4. When acids and alkalis react they form a salt, explain why a salt (in this case NaCl) is a very stable compound? 5. Explain why Sodium is in group 1, period 3 and Chlorine is in group 7, period 3. M1ii Explain in detail how you prepared your base solution, including the calculations. D1i Task 4 – Titrations in Industry Standard solutions are used in the chemical industry to measure and check the strength of chemicals. One particular example is the conversion of WVO (waste vegetable oil) into biofuel for diesel engines. The pH of WVO needs to be altered so it is approximately 8.5, which is the same as normal diesel. Explain how the pH of WVO is measured in an industrial setting and why the pH must be accurately determined. The following websites may be useful: http://en.wikipedia.org/wiki/Titration http://alternativefuels.about.com/od/biodiesel/a/bdtitration.htm D1ii Edexcel Level 3 BTEC Nationals in Applied Science (Forensic Science)Name†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.

The Whiskey Rebellion Essay -- American History

The end of the American Revolution wasn’t the end of political turmoil in the United States. In the years after the Revolution, political parties formed and disbanded, rebellions started, and even celebrations became increasingly political. Each political faction had a different idea of what the Revolution meant and what the future of the country looked like. The conflicting views of American politics began to manifest in holiday celebrations, governmental affairs, and even rebellions. The Whiskey Rebellion was created from many issues, not just the excise tax on whiskey. Farmers in western Pennsylvania blocked roads to prevent tax collectors from reaching them and to show their disdain for the taxes placed on the farmers that they couldn’t pay. Western Pennsylvanians felt democracy was being undermined by the state and nationals governments. They also believed the government favored the wealthy. Revolutionary veterans were angered over the payment of war debt IOUS. Most IOUs had been bought by the upper class, which had to power to demand they be paid in full, while they had paid the original owners of the IOUs a fraction of its value. The government obliged them by creating the Funding Act of 1790 to raise money to pay the war debt IOUs. To protest the unfairness of the government, a militia of about 9,000 troops gathered and began a peaceful march to Pittsburgh. Federalists were worried that what had happened to France (revolution and execution of their k ing) would happen to the United States if protest against the Funding Act and whiskey tax wasn’t put down. The protestors didn’t see themselves as insurgents like the Federalists did. They believed they were defenders of liberty. No force was needed by the government though.

How Do the Sacred Texts and Beliefs of Islam or Christianity Essay

How do the Sacred Texts and beliefs of Islam OR Christianity, inform a Religion that is relevant to contemporary adherents? In todays society, unlike many years ago religion is not seen as an important part of peoples lives. People are way to busy or so they think to be ‘wasting their time’ with religion, and church. But for those who do believe in a religion, especially those from the Islamic religion, they take part in a religion that was formed hundreds of years ago, still using and believing in the same scared texts and beliefs. Islamic environmental ethics are drawn from the 3 underpinning principle beliefs, that are the 3 central concepts of Islam and the pillars of Islamic environmental ethics. Tawhid a belief brought upon many many years ago, is the belief of Unity. It believes in the Unity and oneness of all created by Allah and that unity is reflected in the created world, thus the Tawhid demands that the integrity of the created world be maintained by balance and harmony. â€Å"The whole earth has been created a place of worship, pure and clean.– Hadith The Khalifa, belief in Stewardship, is the belief that Allah has made humans responsible for all creation and with this involves appropriate use of resources for human needs. â€Å"It is He that has made you custodians; inheritors of the earth. † (Qur’an Surah 6:165) Akrah is the belief of accountability, Muslims believe that they will be judged on how they have acted, and ones treatment of gods created world. The sources of ethic al teachings, and the relationship between humans and the universe is outlined in the Qur’an, Hadith and Shari’a. It is defined in Qur’an as based on meditation of the universe and what it contains, sustainable utilization and development for human benefit, care and nurture extended beyond humans to the benefit of created beings. The Hajj is an obligation which fulfils one of the five pillars of Islam required of a Muslim at least once in a lifetime for those financially and physically able â€Å"those who can make their way there†. It is a faithful submission to the will of Allah. And pilgrimage to the House is incumbent upon men for the sake of Allah† – Surah 3:96. Before embarking on this miraculous journey, pilgrims must redress all wrongs, organise funds for the journey and the family being left behind, and prepare themselves for good conduct during the Hajj. The Journey then goes for 5 full days, starting officially on the 8th day of Dhul-Hijjah. After completing the Hajj with all rites performed, pilgrims have earned the right to be called al-Hajj or al-Hajji. The Hajj expresses the beliefs of Islam through commemorating important religious events. These include Abraham and his son Ishmael built the Ka’ba, and established the rituals of the Hajj to reflect his life, Muhammad’s last sermon on Arafat, Jamra symbolises Abraham throwing stones at Satan who tried to dissuade him from sacrificing Isaac, and Nahr reflects Allah replacing Isaac with a sacrificial lamb. The Hajj reinforces fundamental islamic concepts with the Five Pillars of Faith. Shahada, the declaration of faith that there is no god but Allah and Muhammed is the messenger of Allah is expressed through the Hajj by Talbiya (a prayer that states the pilgrimage is only for the glory of Allah) and through Mount Arafat (the place of Muhammad’s last sermon, where all are closest to Allah) Salat, the 5 daily prayers is expressed through the Hajj as the Hajj is a period where pilgrims are directly communicating with Allah and Muslims are in actual proximity of the Ka’ba. Zakat, Almsgiving is shown through the Hajj as the meat sacrificed or money given for nahr is distributed amongst family, friends and the poor, it also shows the obligation of the wealthy to the poor and Ihram, which means that money and status are not a factor for pilgrims and that all are equal. Sawm, fasting is expressed through the Hajj as it is a time of prayer, meditation and asking for forgiveness, as well as the Sa’y as it re-enacts Hajar’s search for food; empathy for hunger. Al-Akhira is believed to be the world to come, Muslims believe in an afterlife where they will be held accountable for their lives (Akhra), they believe that by participating in the Hajj there is a greater prospect of reward in the afterlife. The Hajj is not only significant to the individual but also to the community. The Hajj is significant to the individual as the Hajj is an opportunity for Muslims to experience spiritual rebirth and develop a sense of consciousness in Allah. It is also opportunity to reassess and confirm their Islamic beliefs. The Hajj provides opportunity for the pilgrim to improve their spirituality through worship, hardship and salat. It focuses the individual on jihad; sacrificing time, skills, money and struggling against external evils. Enables the pilgrim’s renewal through cleansing from sin. â€Å"whoever performs the Hajj†¦ will come home like a newborn†. The Hajj reinforces Allah’s mercy and compassion as it exceeds His anger by forgiving the sins of the sinful creation by declaring an absolute pardon for every pilgrim upon completion of the accepted rituals of Hajj. The individual strengthens their relationship with Allah and gains a greater understanding of Islamic history and has a better prospect of reward in the afterlife. The Hajj is significant to the community as the Hajj is a sign of unity, equality and a sense of pride in the global umma as they pray together and are equal in the ihram garments. It brings together Muslims of all races to from a fellowship for such a significant practice in the Islamic faith, and the hajj acts as a universal reminder of the blessing of Allah on humanity of our diversity and the brotherhood to worship the one Allah. As the Hajj and Environmental ethics apply themselves with todays contemporary society, the beliefs and sacred texts are used to form ideas of how to look after the environment and why it is necessary to participate in the Hajj.

1927 - 1928 Academy Awards

The very first Academy Awards ceremony was held on May 16, 1929 at the Hollywood Roosevelt Hotel. More of a fancy dinner than the huge, staged ceremony of today, it was the beginning of a grand tradition. The Very First Academy Awards Soon after the Academy of Motion Picture Arts and Sciences was founded in 1927, a committee of seven members was given the task of creating an Academy Awards presentation. Though the idea was shelved for nearly a year due to other pressing Academy issues, the plans for an awards ceremony presented by the Awards committee were accepted in May 1928. It was decided that all films released from August 1, 1927 through July 31, 1928 would be eligible for the first Academy Awards. The Winners Were Not a Surprise The first Academy Awards ceremony was held on May 16, 1929. It was a quiet affair compared to the glamor and glitz that accompany the ceremonies of today. Since the winners were announced to the press on Monday, February 18, 1929 - three months early - the 250 people who attended the black-tie banquet in the Blossom Room of the Hollywood Roosevelt Hotel werent anxious for the results to be announced. After a dinner of Filet of Sole Saute au Buerre and Half Broiled Chicken on Toast, Douglas Fairbanks, the president of the Academy of Motion Picture Arts and Sciences, stood up and gave a speech. Then, with the help of William C. deMille, he called the winners up to the head table and handed them their awards. The First Statuettes The statuettes that were presented to the first Academy Awards winners were nearly identical to those handed out today. Sculpted by George Stanley, The Academy Award of Merit (an Oscars official name) was a knight, made of solid bronze, holding a sword and standing upon a reel of film. The First Academy Award Winner Wasnt There! The very first person to receive an Academy Award didnt attend the first Academy Awards ceremony. Emil Jannings, the winner for best actor, had decided to go back to his home in Germany before the ceremony. Before he left for his trip, Jannings was handed the very first Academy Award.
