I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for

The objective for the experiment was to perform a reduction reaction on the ketone group of camphor to the OH group on isoborneol. In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical

Spinach was dehydrated using ethanol‚ and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then‚ the solid pigments were run through a column using a non-polar solvent‚ hexane

dissolving the para-aminonphenol hydrochloride salt in water‚ decolourising the aqua solution and crystallising the para-aminophenol by neutralizing the salt. The resulting para-aminophenol is reacted with acetic anhydride to produce paracetamol. The reactions are summarized as shown below: Process using Paranitrochlorobenzene as a starting raw material Paranitrochlorobenzene is converted to paranitrophenol by means of caustic fusion with caustic soda in an autoclave; paranitrophenol thus

EXPERIMENT Materials 200 Toothpicks Timer Tape Controls 50 toothpicks per trial. 120 seconds per trial. The same brand of toothpicks. One toothpick broken at a time (except for Mutation Trial 2). One toothpick broken into two pieces equals one reaction. Broken toothpicks cannot react again. (Toothpicks can only be broken once) The toothpicks are broken between the thumb‚ index‚ and middle finger (toothpickase). Break two toothpicks at a time (Trail 3). Tape the index finger and thumb.

Termite Lab Report The effect of ink on termite behavior Abstract Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas‚ pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones‚ causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen‚ then a termite will be attracted to the path and trace it due to the pheromones
