products begin to form‚ hydrolysis a reverse reaction of esterification occurs. To ensure the reaction is complete an acid catalyst is commonly used. The catalyst is usually concentrated sulphuric acid. This experiment covered 4 techniques; they are distillation‚ refluxing‚ extraction‚ and esterification. Firstly‚ esterification and refluxing‚ the acid and alcohol are first warmed and mixed together with the sulphuric acid catalyst then attached it to a reflux condenser for a period of time. Then extraction

There are many technological solutions that could potentially help to alleviate the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations

Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

This name‚ meaning rock oil‚ is applied to certain bituminous fluids found in the earth. Solid bitumen‚ or asphalt‚ differs but little in chemical composition from petroleum‚ both being compounds of carbon and hydrogen Many varieties of petroleum‚ and perhaps all‚ become thicker by exposure to the air‚ and finally solid‚ resembling asphaltum. Bitumen‚ and doubtless petroleum also‚ was known from the earliest ages‚ being the "pitch" which Noah used in building the Ark‚ and the "slime" used for

Question 2: How can a solid fuel substance like coal be introduced into a steam powerplant? Combustion of coal is C+O2 → CO2. Coal is a solid and a reaction on the surface of the coal (between carbon and oxygen) will occur if carbon is available. This reaction will produce heat (release some chemical potential energy from the
