The specific hypotheses of this experiment was that the iron would separate through magnetism‚ the salt would separate by mixing with water and boiling it‚ the wood chip shavings would separate by filtration‚ and the sand would separate by putting the salt and sand in filter paper.

I performed a number of steps during this recrystallization lab in order to achieve the desired results‚ which included heating the solvent‚ completing a hot filtration‚ completing a vacuum filtration of a chilled solution‚ as well as drying and calculating the weight and melting point of the final version of the sample. I began the lab with 1.5 grams of the impure acetanilide solute and ended the lab with 0.05 grams of pure acetanilide crystals. The percentage of pure acetanilide I recovered during

ARTIFICIAL NEURAL NETWORK: USE IN MANAGEMENT Neuron Transfer Function: The transfer function of a neuron is chosen to have a number of properties which either enhance or simplify the network containing the neuron. Crucially‚ for instance‚ any multilayer perceptron using a linear transfer function has an equivalent single-layer network; a non-linear function is therefore necessary to gain the advantages of a multi-layer network. Types of neuron transfer function • Pure Linear Transfer Function

Overall‚ this experiment consisted of over seven parts however‚ because of the amount of time given in summer lab we had to save time and cut some days out. We were able to do this by being given our own Salicylic acid (SA) prepared for us instead of having to used wintergreen to make it and recrystallize it. In addition‚ we skipped the qualitative test of our purity for SA and Aspirin (ASA). The first part of this experiment is the preparation of ASA from SA were‚ we prepared our aspirin from the

Then you will set your filter to rinse allowing water to go back through the filtration system allowing it to clean any debris from the sand. Then you will take a skimmer net and clear anything left off the top of the water (Now it is on to the most critical part) II. The chemicals and filtration system. A. You may have one of two types of filtration systems; there

The Chinese Room is a thought experiment developed by John Searle. Searle imagines himself in a room receiving pieces of paper inscribed with Chinese symbols through a slot. Searle himself does not understand any Chinese. Searle locates the set of symbols he receives in an English instruction book and then sends out the corresponding set of symbols representing a response as identified in the book back through the slot; similar to how a computer follows the instructions of its program.
