These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

1. Functions of Soap Soap primarily serves as a dirt remover and a cleanser. It is used in bathing‚ cleaning‚ and also as a lubricant. Oil‚ grease‚ and other forms of dirt do not dissolve in water. Conversely‚ soap can suspend these in such a way that it can be discarded through its ability to act as an emulsifying agent. This emulsifying agent enables the dispersion of liquid into another immiscible liquid. In this manner‚ oil does not mix with water whereby able to induce dirt. 2. Raw materials

split by hydrolysis into more simpler sugars. The carbohy-drate content can be measured by hydrolysing the polysaccharides into simple sugars by acidhydrolysis and estimating the resultant monosaccharides. PRINCIPLE Carbohydrates are first hydrolysed into simple sugars using dilute hydrochloric acid. In hot acidic medium glucose is dehydrated to hydroxymethyl furfural. This compound forms with anthrone a green coloured product with an absorption maximum at 630 nm. MATERIALS 2.5 N HCl Anthrone reagent:

osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable to starch. 4B- The hypothesis was supported because the diffusion rate was faster shown from the agar blocks. The materials passed through the membrane
