Micro-Reactions: Predicting the Products of Double Replacement Reactions Introduction – A double replacement reaction is a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound. If you have the reactants of two reaction solution that you can determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

Comparing democracies There are four major factors that contributed to the new interest in comparing democracies that is the comparison of regimes‚ the ‘third wave’ of democratization‚ institutional engineering‚ and the last one is Neo-institutionalism. The first factor comes from the study of Powell (1982) and Lijphart (1984) that has characterize and compare democratic regimes as a whole. Lijphart has elaborated the distinction of the majoritarian and the consensus models of democracy to

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

Good Times & Bad Times Life! I still do not have the exact concept of what life is exactly and what one values the most in his/her life. But what I do know is that our life is comprised of several ups and downs. Those ups are valued as good times when life continues easily with less complications and the downs are bad times when life becomes harder and more complicated. No matter how wealthy we are or what position we hold‚ we ought to face both bad and good times one after another. I think happiness

Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2.

Comparing and Contrasting (quoted from Jim Stover‚ “Writing About Literature”) One of the best methods to help us clarify our thoughts about a character‚ an event‚ a poem‚ a story—nearly anything—is to compare and contrast. (To compare can mean to find similarities and differences. Coupled with contrast‚ however‚ to compare means to point out similarities‚ while to contrast means to point out differences.) Many of us‚ feeling weighted down by cares‚ have happened to see someone coping with a

Comparing Authors William Shakespeare and W.H. Auden are widely known for their great poems. Shakespeare’s “My Mistress Eyes are Nothing Like the Sun” is a love unlike any poem from the Elizabethan era. Shakespeare does not use false comparisons to describe his lover like most love poem do‚ which is refreshing. W.H. Auden’s “Funeral Blues” is another love poem that is little gloomier. However it shows how much death can affect an individual’s life. Together Shakespeare and Auden use similar and
