Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

Burning Money Chemistry Demonstration Principle You soak a note in ethanol (alcohol) and it will burn when lighted‚ leaving the note untouched. This is because alcohol is more flammable‚ and burning alcohol causes it to vaporize‚ along with the water present in the solution. This removes heat from the note and prevents it from reaching its combustion point.
