Genius is one percent inspiration‚ ninety-nine percent perspiration. * Spoken statement (c. 1903); published in Harper’s Monthly (September 1932) * Variants: * None of my inventions came by accident. I see a worthwhile need to be met and I make trial after trial until it comes. What it boils down to is one per cent inspiration and ninety-nine per cent perspiration. * Statement in a press conference (1929)‚ as quoted in Uncommon Friends: Life with Thomas Edison‚ Henry Ford‚ Harvey

Experiment 5: Percent Water in a Hydrated Salt Chemistry 1300 Instructor: 2/8/12 Abstract: The purpose of this experiment was to determine the percent by mass in a hydrated salt‚ as well as to learn to handle laboratory apparatus without touching it. The hydrated salt‚ calcium carbonate‚ was heated with high temperature to release water molecules. Gravimetric analysis was used in this experiment to determine the percent by mass of water in a hydrated salt. The hypothesis of this experiment

of reacting increases; resulting in a greater amount of NaCO3 reacted and greater generation of CO2. Percent by mass of NaCO3 that has reacted can be determined by using mass difference and dimensional analysis to relate the amount of CO2 produced to the amount NaCO3. Collective class data are exhibited in Table 1‚ and Figure 1 renders the class findings in a plot. As shown in Figure 1‚ the percent by mass of Sodium Bicarbonate in the Alka-Seltzer tablet primarily increased along with the volume

Ideally‚ the percent yield should be 100%‚ as this means that you have recovered 100% of that material. A yield over 100% would mean that the substance still has some traces of another material that is adding additional mass. Ex. The iron filings having some sand particles leftover. A yield under 100% would mean that some of the substance was not recovered‚ it could have been lost (spilled) or found in another substance (not separated completely). The percent yields may give some insight into what

Chemistry 217 Dr.Rudolf Rednose Tues/8am/S-473 Determining the Percent Oxygen in the Air INTRODUCTION: Recent tragedies in coal mines have exemplified the importance for us humans to breathe an adequate amount of oxygen if we are to survive. But what amount of oxygen is adequate? How can we know the amount of oxygen present in what we consider fresh air? The purpose of this experiment was to determine the percent oxygen typically present in air. The conclusion of the test suggested that
