    INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual

    Sodium was first discovered by Sir Humphrey Davy in 1807. This element is the 11th element found on the periodic table; located in group 1 and period 3. Its chemical symbol is Na and it is classified as a metal. Metals‚ by definition‚ means that they are elements that are luster‚ lose electrons very easily‚ malleable‚ ductile‚ and are great conductors of heat and electricity. Sodium is found in group 1 of the periodic table because the electronegativity of sodium is very low. This allows it to form

    In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many disks of spinach leaves float at the end of every ten minutes. Our main focused and question was how using different amount of concentration of sodium bicarbonate would affect the process

    PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol

    and the sodium hydroxide. When using glassware in experiments‚ it must be flushed out to make sure that cross contamination does not happen and that the only thing that would then be coating the beaker is the distilled water. When all of the glassware has been cleaned‚ some sodium hydroxide should be placed in a plastic weighing boat next to the scales and place the second weighing boat on the scales and weigh it then click the on tare button to set it back to zero and weigh out 1g of sodium hydroxide
