Boiling

that you have overlooked your kitchen’s sink. That food waste that is stuck in the pipe or garbage disposal could be the source of the fruit flies. Here are some ways to get rid of them. Boil Water or Vinegar An easy method to start with is to use boiling water. Simply pour it into the drain to kill all those pesky fruit flies. As an alternative, you can also boil apple cider vinegar with…

property of water is that it has high melting and boiling points . This means that water has a high specific heat which is why it takes up a lot of heat before its temperature increases and loses a lot of heat before its temperature decreases. This characteristic is very important as it contributes to the moderation of the earth’s temperature and the moderates the internal temperature of all living organisms . The reason why water has a high boiling point is because in order to evaporate water,…

is setup by adding 25.0 ml of 2-methylcyclohexanol in a 100-ml round bottom flask and to this 10 ml of 9 M sulfuric acid is added which acts a catalyst to this reaction. The content is swirled is completely for about 2 minutes periodically. Then 3 boiling chips is added to the mixture, now starts the fraction distillation. The mixture is heated with a heating mantle for distillation to occur. It is heated until 10-ml of the mixture remains in the reaction flask or less than 100°C. The organic…

Fahrenheit, commonly known as a unit of measurement for temperature which is regarded as an official scale in the modern society of the United States and other Caribbean countries. It is the first standardised temperatures scale which was adopted globally in the seventeenth century. This great invention is named after a German science instrument maker, Gabriel Fahrenheit (1686- 1736). His invention has revolutionised the design of thermometer in 1724 when he conducted the first mercury…

vaporizing a substance or a mixture; condensing it through the water condenser and then collecting it in the receiving flask1. In this experiment, fractional distillation is used to separate organic compounds that have a minuscule difference of their boiling points. The objective of this experiment is to purify and separate ethanol and water by fractional distillation to achieve the 95% of ethanol and 5% of water; then determine the density of the liquids that were collected. In the experiment,…

cover and let it stand covered for 2-3 hours . After that add in the water. The bath will stimulate circulation and effectively act against cellulite. Hair Lotion of leaves and roots of nettle 2 tablespoons nettle leaves 2 tbsp of nettle roots 4 dl boiling distilled water 1.5 dl of 70% alcohol; Chopped fresh leaves and roots or half the dry pour the hot distilled water and leave covered overnight. Strain, add alcohol, shake and every 2-3 days scattered through the scalp and hair. Leave for 1…

occur when the hydroxyl group bonds with the third carbon atom of the chain. Both primary and secondary alkanols can be oxidized however tertiary alkanols cannot (ausetute, NA). As the number of Carbon atoms in the carbon chain increase, so does the boiling point of the fuel. Primary and secondary alkanols undergo complete combustion when burned in the presence of…

nuclear power plants: boiling water reactors (BWR) and pressurized water reactors (PWR). Boiling water reactors boil the water around the nuclear fuel, heating it into steam and then carry the steam directly to the turbine which dives the generator and produces electricity. The unused steam is recycled back into water and used again in the same process. Pressurized water reactors heat water surrounding the nuclear fuel but keep the water under pressure to prevent it from boiling. This hot water…

Potassium Permanganate Test: 1. Three drops of the compound to be tested are dissolved in 2 ml of water or aqueous ethanol. 2% KMnO4 solution (a purple solution) is added drop wise and the solution is shaken. 2. The purple color of the KMnO4 solution disappears and a precipitate of MnO2 is formed. A negative test is if there no precipitate. 3. Repeat for every unknown and record observations. Observations and Results Water Solubility Test: When the test was conducted and observations were made,…

simple distillation was used and the result wasn’t as expected. The boiling point of the alcohol product wasn’t the boiling point of the expected alcohol 2-methyl-2-pentanol. The boiling point of 2-methyl-2-pentanol is 120-122oC (ref.6); however, the boiling point of the alcohol product was about 76-80oC. Simple distillation is useful if the difference between 2 products boiling point is more than 100oC; however, the difference of boiling point between ether and 2-methyl-2-pentanol is less than…
