Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

longer or shorter‚ in other instances a covalent bond may be broken. These changes depend on the energy of the light absorbed by the molecule (which is proportional to its wave number and inversely proportional to its wavelength). From the relationship E = hc / λ‚ we can calculate that longer¬–wavelength visible light (400 to 800 nm) is less energetic (70 to 40 kcal/mole) than Ultraviolet light (200 to 400 nm; 150 to 70 kcal/mole). Consequently‚ ultraviolet light is most often effective in producing

Reynolds number basically determines the transition of fluid flow form laminar flow to turbulent flow. When the value of Reynolds number is less than 2300‚ laminar flow will occur and the resistance to flow will be independent of the pipe wall roughness (e). Meanwhile‚ turbulent flow occurs when the value of Reynolds number is exceeding 4000. For large viscous force‚ whereby Re value is less than 2300‚ viscous effects are great enough to damp any disturbance in the flow and the flow remains laminar. The

Experiment E: Post lab Natasha Buckiewicz (130361780) IA: Matt Halloran Due: November 26‚ 2014 1. This experiment followed GCP number 8 which is reduce derivatives. This experiment did not use unnecessary derivation since the reaction was not modified in any way. No additional reagents were required so it did not generate a lot of waste. 2. Safer solvents and auxilaries (GCP #5) was not used in this experiment since the experiment used a solvent to complete the reaction. The reaction used both

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
