INVESTIGATING THE DIFFERENT RELATIONSHIPS THAT CONCENTRATION AND TEMPERATURE HAVE ON THE RATE OF REACTION Aim To study the effect that temperature and concentration of iodide ion solution have on the rate of iodide ion I⁻ oxidation by peroxodisulphate ion S₂O₈⁻‚ creating an iodine clock reaction. Introduction I decided to choose as the topic for my investigation the rate of reaction for its vital importance in the human body. Indeed I am really interested in Biology and especially physiology and

pressure is due not to static repulsion between molecules‚ as was Isaac Newton’s conjecture‚ but due to collisions between molecules moving at different velocities through Brownian motion. While the particles making up a gas are too small to be visible‚ the jittering motion of pollen grains or dust particles which can be seen under a microscope‚ known as Brownian motion‚ results directly from collisions between the particle and gas molecules. As pointed out by Albert Einstein in 1905‚ this experimental

"Inti"‚ this is also the second Peruvian currency. The foundation of the Empire was attributed to the Inca Manco Capac in the thirteenth century. The last emperor Atahualpa was executed by Francisco Pizarro in 1533 in the city of Cajamarca. The Inca emperors were able to maintain and develop its vast domain‚ due to the concern for the welfare and happiness of his subjects. They did not know about hunger and injustice; their system had been called paternalistic Empire because it was

their own. Pizarro’s capture of Atahuallpa and destruction of the Incas made the Europeans realize what power they head‚ and what they could do to the rest of the world. They easily wiped out the Inca’s of 80‚000 with 168 men. From the Battle of Cajamarca‚ Pizzaro came back to Charles I saying that Europe had the power to conquer the Americas. There were reasons Pizarro and the Europeans could conquer the Americas… They had better warfare than the Incas. Pizarro’s men had armor rode horseback and

aggravated assault that occurred in a collision during a recreational non-contact ice hockey game. The appeal was upheld in the Ontario Court of Appeal in a decision written by Hourigan J.A.‚ reasoning that the trial judge erred through impermissible speculation to reach their verdict. The appeal concerns a collision between the appellant‚ who played for the Tiger-Cats and the complainant‚ who played for the Pirates. In the final 47 seconds of the game the collision occurred resulting in the complainant

On impact the first puck continued in motion and initiated the motion of the second puck. The collision was filmed on the video camera. After this a second experiment was set up with the same two pucks‚ but this time they were placed in either corner of the air hockey table. They were launched at the same time into the centre of the table‚ where they collided and bounced off each other and this collision was also filmed. In the final experiment the two pucks were replaced with larger pucks with Velcro

Airbags were produced to help save the lives of people in automobile collisions and accidents. Whether it be to save a small child or a full grown adult‚ the goal remains the same. For these life-saving contraptions to work‚ a series of chemical reactions must take place. Such as the chemical reaction of the decomposition of the hazardous chemical‚ sodium azide. The decomposition of sodium azide goes on to produce nitrogen gas‚ which fills up the air bag in order to protect the victim in the driver’s
