turned on. The batch reactor was started to ensure the conductivity probe was functional and the reading was displayed on the PC. 500mL of ethyl acetate was then added to the reactor‚ which was maintained at approximately thirty degrees Celsius by a water bath. As soon as the ethyl acetate was added‚ the conductivity and temperature were measured at two minute intervals until the conductivity plateaued‚ indicating the point of maximum conversion for the reaction.

Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the

This novel was written in the nineteenth century by the Philippines’ national hero‚ Dr. Jose Rizal‚ then an expatriate in Europe waging a propaganda campaign against tyranny and oppression in his native land. It is a sequel to his earlier work‚ Noli Me Tangere‚ a socio-political novel that depicted the conditions in the Philippine Islands - a colony of Spain for three centuries - under the Spanish yoke.

the total annual demands increased every year. This increase was from both sides of the demands‚ Exports and Domestic‚ especially the latter in later years of this period. From economics theory we know that increasing demands lead to increasing price. Increasing price leads to increasing supplies. In order to meet with the increasing demand‚ manufacturers needed to raise their supplies. As a result‚ this increase in manufacture required more capital investment.

Lead is a naturally occurring element found in small amounts in the earth’s crust. Although it has some beneficial uses‚ it can be toxic to humans and animals causing health effects. Lead can be found in many places‚ much because of human activity through burning fossil fuels‚ mining‚ and manufacturing. Lead and lead compounds have been used in a wide variety of products found in and around our homes‚ including paint‚ ceramics‚ pipes and plumbing materials‚ solders‚ gasoline‚ batteries‚ ammunition

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline
