of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield benzoin. Thiamine catalyst

You have to know what the products and reactants are. 2. What observations might you make that suggest that a chemical reaction has occurred? If a gas is produced or precipitates are formed that indicates chemical reaction. Also‚ if color changes occur or

Experiment 9 and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution‚ volumetric analysis was used. In volumetric analysis‚ a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4

A Penny Saved Is Two Pennies Wasted The United States of America‚ despite its relatively short life‚ is immersed in tradition. While some of these traditions are well-known and apparent‚ others are less obvious. The penny‚ our little copper one-cent piece littering change jars from coast to coast‚ is a tradition that‚ while seemingly harmless‚ is a great burden to our country. Due to the lost profits in the creation of today’s one-cent piece and using the models of previous successful countries

Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group.

pockets or purses for a few pennies? All they have is just unwanted weight to their pockets and purses. Few people now a days still bend down to pick up a penny off the sidewalk. Whether its the superstions of “luck” or just another penny to add into their collection. Only traditions explain our stubborn attachment to our pennies. However‚ pennies should not be abolished‚ they are beneficial to us in every days life. For example‚ people who have thousands of pennies saved up from over the years

April 10‚ 2013 The Penny The use of pennies is steadily declining. Most people don’t even keep track of the amount of coins they have‚ so it’s more than likely that they’ll think it’s useless‚ and dispose of it. People would throw away the pennies they have‚ without a second glance. Bit if we all save up our loose change‚ there’s a chance we’d be able to save up to hundreds‚ or possibly even millions of pennies. Pennies are valuable to some people‚ for example‚ coin manufactures (Source

(explain why you have chosen to investigate this particular topic) I have chosen to examine this experiment as it applies to our daily lives. Rusting of metal occurs every day whether it’s the nails on our deck or that rusting bicycle in our garage. Considering that rust is such a worldwide problem‚ I wanted to conduct my own explanation. Another reason why I picked this investigation is because I enjoy chemistry and believed it would be a worthwhile experimentation. 3. Background information (very briefly
