Isolation Of Rubber Seed Essay
CHAPTER FOUR RESULTS 4.1 The effect of drying rubber seed Figure 4.1 The effect of weight of samples before drying and after several hours The result shown in Figure 4.1 indicated that the moisture content of both rubber seed samples. From the results, it obviously indicates that rubber seed kernel weight constant after 6 hours drying while the rubber seed kernel weight remains constants after 3 hours only. The decreasing rate of drying affects the moisture content as well as decreasing. The purpose of drying is to regulate the moisture content and to get high production in oil extraction. 4.2 The moisture content of rubber seed Figure 4.2 the effect of moisture content on the rubber seed shell and rubber seed kernel …show more content…
Whereas, in the case samples of rubber seed shell, the oil yield shows a little amount of extraction. Figure 4.6 the boxplot of oil yield based on solvents use From ANOVA result, the p-value for factor solvents is less than 0.05. This indicates types of solvent use does affect the oil production significantly. This also indicates both of solvents are effective in pressing out the oil from rubber samples. From the graph 4.4 and 4.6, it can be obviously seen that using ethanol gives higher oil yields than conducting solvent extraction using hexane. Moreover, oil yields also higher with extraction using ethanol solvent toward both rubber seed samples. The yields of oil extracted with the ethanol (a polar solvent) were significantly (P≤0.05) different from that of the oil extracted with hexane (non-polar solvent), having a yield of 59.97% (ethanol kernel) and 23.02% (ethanol shell) while the amount of oil extracted by the polar solvents ranged from 37.07 (hexane kernel) and 1.67 (hexane shell). 4.5 Gas Chromatography-Mass Spectrometry (GCMS) analysis Figure 4. the GC-MS chromatogram of rubber seed kernel oil Retention time (min) Group Class of compound

For this lab the research questions is mixture, homogenous mixture, and heterogeneous mixture. A mixture is a combination of 2 or more substances that are mixed together physically but not combined chemically. Also a homogeneous mixture is a uniform in structure or composition throughout the substance. Lastly, a heterogeneous mixture is a consisting of dissimilar parts of elements (not the same).
Duckweed Lab Report
1462 Words | 6 Pages• N. Dirilgen, 1994, Cobalt-copper and Cobalt-zinc effects on duckweed growth and metal accumulation. Different concentrations of Cobalt2+, Zinc2+ and Copper2+ as well as Co2+Cu2+ and Co2+Zn2+ were added to nutrients given to a species of duckweed, Lemna minor L. the effects of these metals on the growth of the duckweed was recorded. A change in growth was not very noticeable until the concentration of Cobalt (Co) and Copper (Cu) reached 2.00 ppm (parts per million), where the growth of the duckweed was inhibited. It was also discovered that Cu and Co work together to inhibit growth when they are at a certain concentration, and at other concentrations, the one would neutralise the other, creating less of an effect on the growth of the duckweed. The conclusion the I took from this study is that as the
Isolation In The Chrysanthemums
1163 Words | 5 PagesIsolation at the Heart of Gothic Literature One of the key aspects of Gothic literature is the idea of isolation from "normal" society, in desolate settings like haunted buildings and remote valleys. These allow the characters to behave in other ways than the norm and in some cases to experience the supernatural through the power of their imagination and fears because of the lack of the normalizing influence of society. In all of the following examples the leading women of the stories are confined within a realm of their own femininity and in physically isolated environments that reflect this state of mind. In The Chrysanthemums John Steinbeck utilizes the setting as a way to highlight the protagonists loneliness.

Rhubarb Osmosis Lab Report
1127 Words | 5 PagesAdditionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.
Summary Of An Indian Father's Plea By Robert G. Lake-Thom
225 Words | 1 PagesIn “An Indian Father’s Plea” by Robert G. Lake-Thom, Lake-Thom uses transitions to help connect his ideas and create a well written essay. In the twelfth paragraph the author discusses the knowledge that his son possessed before he began going to the school he is currently attending. Since Lake-Thom is listing the knowledge his son possessed before starting at that school he uses the transitional expression “and” frequently in this paragraph. Lake-Thom also repeatedly uses the transitional expression “but” when he says that while his son may not be able to do something that other non-Indian children his age can do such as writing their names he has knowledge of other things that those children don’t have. He also begins multiple sentences with

Radish Plant Experiment
924 Words | 4 PagesAbstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary

Gas Chromatography Lab Report
1545 Words | 7 PagesIf the sample to be analyzed is non-volatile, the techniques of derivatization or pyrolysis GC can be utilized. Gas chromatography (GC) has been an indispensable analytical technique in the application of fatty acid determinations in oilseed plant breeding, biosynthesis, and human metabolism. As well as the characterization of complex mixtures of geometric isomers when combined with other chromatographic separations and spectroscopic identification. Plant cultivators utilize GC as a more accurate and fast method to evaluate the differences and inheritance of fatty acids in oilseed crops such as rapeseed. flaxseed, and safflower.
