one-word topic "Love". This piece was written in 45 minutes (actually I had more time‚ I but I wasted too much time - some of it unnecessary - to think of what to write)‚ so mind you‚ I was in quite a hurry. Personally‚ I don’t think it’s that good... I really wish they gave us more time for this written paper for English. Could’ve produced a better essay with more time‚ I think. So anyway‚ here you go. Comments will be appreciated. Love (SPM Trial Exams Essay) by Lee Zhi Wei Love. It is the one

“Love for another often hides a greater love for oneself” By a close comparison of your two texts‚ discuss the representation of sex and seduction. In both Milton’s ‘Paradise Lost’ and Ford’s ‘Tis Pity She’s a Whore’ sex is represented as a catalyst for sin. The love which is promised by many of the central characters in the poem and the play often has a falsehood and is used as a facade for the character’s true egotistic needs within. One can see a falsehood in Giovanni’s admitted love for

When a really large unstable isotope changes into to smaller isotopes that are 2 completely different elements. the nucleus has to be larger than 230(mass). They are really slow and spontaneous. Fission = splitting. Can create a chain reaction. (picture above). Critical mass= must be enough mass in a reaction or enough fission type mass‚ fissionable mass‚ for the reaction to continue to go on.(minimum amount). Sub critical mass= mass of fission material that doesn’t have enough to keep the reaction

INTRODUCTION: The purpose of this experiment is to measure the formation constant of the tetraamminecopper(II) ion by colorimetry. Anhydrous copper sulfate (CuSO4) is white‚ which means that it does not absorb light in the visible region of the spectrum. The hydrated copper sulfate (CuSO4 - 5H2O) is blue. The structure of the compound can be represented more accurately as Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. The

Article Excerpt Access to the world’s oil supplies is a principal factor behind US government policy‚ as the events of the past two years have unmistakably shown. And no wonder: possessing only 2% of the world’s reserves of oil‚ the US consumes 25% of global oil production at a cost of $150bn per year. Of this‚ 70% is in the form of gasoline (petroleum) or diesel fuel for transport use. Given the finite supply of oil‚ this cannot go on. Certainly‚ by 2050‚ competition for oil supplies will be

Unit _ - Control of Air Pollution FABRIC FILTER – It consists of a tabular bag which is closed at the upper end and has a happer attached at the lower end to collect particles when they are dislodged from the fabric. Many such bags are hanged in a bag house. The filter bags are cleaned occasionally by a mechanical shaker for efficient filtration. It has high efficiency and can filter 0.5 µm size particles. ELECTROSTATIC PRECIPITATOR – It works on the principle of electrostatic precipitation

3.1 a) Valence electron: Valence electrons are the electron in the outermost electron shells of an atom. They are generally the electrons involved in chemical reactions and bonding with other atoms. b) Lewis electron: It is a structural demonstration of a molecule where you can use dots to show the position of the electron around the atoms and lines. c) Octet rule: It is referring to the principle that bonded atoms share their eight outer electrons. There rule of the octet is sometimes broken

Assessment 1) Describe the difference between ionic and covalent bond. Ionic bonds have electrostatic forces that hold cations and anions together‚ and are electronic neutral. Covalent bonds are bonds that don’t give or take any electrons. In stead they share the elctrons 50) Which of these compounds contain elements that do not follow the octet rule? Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d”
