An investigation in to the rate of reaction Plan: I am going to investigate the rate of reaction. The reaction I will be using is: Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide. CaCO3 + 2HCl ---- CaCl +H2O + CO2 Measurements and Variables: The variables I have chosen to change is strength of the hydrochloric acid which will be 1 mole‚ 0.7 mole‚ 0.5 mole‚ 0.3 mole and 0.1 mole some variable I will not be using are temperature‚ mass‚ density. The measurements

Argument essay Chip or Not to Chip? In 2006‚ 44-year-old William Koretsky was unconsciously taken to the hospital after he was in a serious car accident. An emergency room scanner revealed an implanted Radio Frequency Identification Device (RFID) chip in his arm. Doctors identified and reviewed Koretsky’s health history using an online database‚ to learn that he had type-one diabetes. Physicians quickly began monitoring his blood sugar level while treating his injuries. According to the 2006

How does acid precipitation affect marble and limestone buildings? Acid rain is a type of precipitation that is characterised by containing contaminating substances such as sulphuric and nitric acid‚ both of which have harmful effects on the environment. Both marble and limestone are extremely vulnerable to the damages done by acid rain due to their components. These materials contain calcite‚ a substance that easily reacts and dissolves with acid. Acid rain is the cause of the destruction of many

and put it in their own museum for visitors to see. This document has so much importance to the United State of America and it just would not be right for someone else to be showing it off. This is the issue that has risen with the Elgin Marbles. These marbles hold such a large part of Greek history and art but they are being seen by others in the British Museum. The Greeks have tried for decades to get these important items returned but the British Museum just does not want to let them go.

period‚ as it showed an amount of cream measured (fat) that the cows would produce (L. L. Van Slyke‚ 1906). The chemistry behind the Babcock test is that by using the sulphuric acid it will burn all liquid except for the fat. The sample is then added with deionised water then placed in the centrifuge determining the layer of fat (University Kentucky‚ College of Agriculture‚ 2013). Sulphuric acid is important in this method as when it is added this increases the process of the fat layer appearing

To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of
