Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

In this practical an electroencephalogram was carried out. An electroencephalogram (EEG) is a test that measures the brain waves and electrical activity of the brain by way of field potentials. It is used in both awake and asleep states. The human brain allows functions of various mechanisms to occur by communication within the brain. The communication within the brain is done through neurons of various sorts‚ sending action potentials through various regions. Each region in the brain will have specific

with life’s challenges‚ as it was displayed in the book The Wave’ written by Morton Rhue. There were a majority of students who were not resilient with the wave and the challenges that emerged from it‚ such as Amy‚ Robert and David. The student that was surprisingly resilient was Laurie‚ who was also the main character of the story. Laurie was mentally and also physically strong at dealing with the consequences that upshot from the wave Such as the isolation from the entire school and her best friend

cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

The Wave 1. Was Mr. Ross right or wrong in manipulating his students as he did? Defend your answer. Mr. Ross was wrong in manipulating his students. I believe that because his manipulation caused many things to go wrong and many people got hurt with it too. When he finally ended in what he had done‚ it affected all the Wave members greatly in which many students like Robert might have done something to his life if the movie continued on or so I think. Many people were even getting hurt
