Abstract: The objective of this lab is to calculate the theoretical‚ actual‚ and percent yield of the product from a precipitation reaction. It is also to learn concepts of solubility and the formation of a precipitate. The Experiment and Observation: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small paper cup. Then add

the Burnay jars of Ilocos are the only large clay jar manufactured in Luzon today with origins from this time. The Portuguese were the first European explorers who recorded it in their charts as Luçonia or Luçon and inhabitants were called Luçoes.[10] The Spanish arrival in the 16th century saw the breaking up of these kingdoms and the establishment of the Philippines with its capital Cebu‚ which was moved to Manila following the defeat of the local Rajah Sulayman in 1570. Under Spain‚ Luzon

energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy‚ and a phase may change‚ such as in melting and boiling. Thermochemistry focuses on these energy changes‚ particularly on the system ’s energy exchange with its surroundings. In combination with entropy determinations‚ it is used to predict whether a reaction is spontaneous or non-spontaneous‚ favourable or unfavourable. Chemical reactions can be divided into two based on the

Conclusion This survey that represents the largest compilation of results ever presented on BeHardware.com‚ gives a good idea of developments since 2005‚ the date when the first dual core models were launched by AMD and Intel. Moving from the 90nm engraving that was used then to 65nm and then 45nm has allowed the two chip makers to move on to quad core models with availability at under 100 euros. Performances have increased by a factor of more than 4‚ while over the same period energy consumption

Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After performing the reactions‚ you
