Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

Conclusion about sparkly islands The geographical location of the South China Sea is very important. It is a route that fishermen must take‚ is rich in fishery resources and has very rich petroleum reserves. This has made it a bone of contention between the countries in the region‚ resulting in a never-ending conflict‚ especially in the Spratly Islands. Each littoral state has occupied islands as a means of declaring their sovereignty over them‚ so there is a high level of tension in the area

Section Assignment 3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module

Aim: To find out the mass of Iron (II) sulphate each ‘Iron tablet’ contains Background Knowledge: ‘Iron tablets’ are prescribed to patients suffering from anaemia. They contain 200mg (0.200g) of iron (II) sulphate FeSO4 We are going to analyse iron tablets to find out how much Iron (II) sulphate they contain. The procedure we will use is a REDOX reaction‚ by oxidising the Fe2+ contained in the Iron (II) sulphate to Fe3+. We will use potassium manganite (VII) as the oxidising agent. The active part

In our hypothesis we predicted that the enzymes in the pineapple will denature when the temperature is changed. The prediction was partly correct. Pineapples have special enzymes that denature gelatin molecules. Which is the reason why the pineapple and gelatin test tube remained filled with liquid‚ instead of turning into jelly which gelatin does when it’s molecules are not disturbed. Why our hypothesis was partly incorrect was lacked depth in that when changing the temperature by heating the pineapple

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

The iron triangle is an alliance made up of 3 groups‚ bureaucrats‚ Congress and interest groups. All of these three groups have common goals that they work together to achieve; also they each have their own individual‚ personal goal. An example of this would be how interest groups seek to promote their ideas‚ in order to do this they will lobby Congress and Congress will try to help in order to gain support‚ meaning votes from their constituents‚ along with promoting their own ideas that they have

This post is the thoughts and points. after today’s lecture (8/31). In the novel‚ Like Water for Chocolate‚ by Laura Esquivel‚ love tensions and rebellion play a role into both the theme and the plot. The popular TV reality show and “soap opera” like content‚ The Bachelorette follows one lady looking for love in the mist of many male suitors. In this instance‚ Tita‚ is the contestant. She narrowed it down to her final two‚ John Brown and Pedro. Let’s get to know our contestants background. John Brown

Title: Determination of Iron in Natural water by Spectrophotometry. Aim: To determine the iron in natural water by spectrophotometry. Abstract: The iron in natural water was determined by utilizing spectrophotometric analysis. That was done by measuring the absorbance of five Fe(oPH)2+3 standards at 510 nm. From that information‚ a calibration curve was plotted and used to find the amount of Fe2+ that was in two unknown water samples based on the absorbance readings obtained with them at 510nm. The
