Using the Iodine clock method to find the order of a reaction Introduction When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below: S2O82-aq+ 2I-aq SO42-aq+ I2(aq) The reactants and the sulfate (VI) ions are colourless however the Iodine is a yellow/brown colour. This allows you to measure the progress of the reaction through the colour change when the iodine is produced. In order to determine the order of

There are four reasons why Alexander Hamilton argued in favor of the development of manufacturing. His first reason was that manufacturing would help the economy. The economy would grow financially and manufacturing would cause more trade. His second reason was that manufacturing would bring down tariffs‚ which would cause more trade and jobs. His third reason was that manufacturing would bring more immigration to the “Young America”. With the new population it will expand America and open more areas

Larry Rooney Mr. O’Shea US History November 29‚ 2012 Jefferson Vs. Hamilton During the years after the Revolutionary War‚ the founding fathers introduced a very weak form of government through the Articles of Confederation. These articles were created to give more power to the states than the federal government. Eventually‚ the Constitutional Convention was called to edit the Articles of Confederation‚ but the members of this convention completely gutted the documents. This led to the development

Subject: Chemistry SL Title: Preparation of a salt (lead iodide) by using precipitation method. Aim: To produce 1.50 g of lead iodide‚ PbI2‚ assuming 100 % conversion‚ using 1.00 g solid potassium iodide‚ KI‚ and 0.1 M lead nitrate‚ Pb(NO3)2 solution of volume 30 cm3 and hence calculate percentage yield. Calculations: 2KI(s) + Pb(NO3)2( aq) —> PbI2 (s) + 2KNO3 (aq) Mass of PbI2 to be produced = 1.5 g Moles of PbI2 = = 0.003 Moles of KI = 0.003*2 = 0.006 Mass of KI = 0.006*166 = 1.00 g

Alice Hamilton was a very intelligent woman who dedicated her life to helping improve the lives of others in the world. She worked many years as a physician and became a leading authority on lead poisoning and other industrial diseases. Hamilton spent her life improving the safety standards of factory workers nationwide by studying occupational illnesses‚ toxicology‚ and the dangerous effects industrial metals and chemicals have on the body. In 1869‚ Alice Hamilton was born in Fort Wayne‚ Indiana

When doing research nurses have come up with theories to expand nursing practice and these theories help ideas to be composed. Theory backs and puts forward research problems‚ research discoveries confirm or disprove theory explanations‚ as stated by Borbasi and Jackson‚ (2012).The research article that I have chosen for this assignment is from International Journal of Nursing Practice. It is a qualitative study that was written by King and Walsh‚ (2007) and the topic is ‘I think PCA is great‚ but

Federalist Paper No.15 expressed how he felt about the people and the government. Hamilton argued non-stop about the Constitution problems and how he would like to solve them. Hamilton had his own beliefs‚ fears‚ and assumptions about the arguments he faced with the Constitution‚ but he was not afraid to speak up and speak out about how he would solve them himself. In the Federalist paper No. 15‚ Alexander Hamilton argues that a stronger central government is needed‚ and he believes that without

founding fathers‚ Thomas Jefferson and Alexander Hamilton‚ both had different visions for American Society. Thomas Jefferson‚ the third president of the United States‚ believed strongly in an agricultural society for America and wrote “The Importance of Agriculture.” In his writing he spoke about why an agricultural society would be so beneficial and how industrialization would hurt the people’s values. Although‚ contrary to Jefferson’s vision‚ Alexander Hamilton‚ the first secretary of state‚ believed in
