amongst it all. Being that the novel has a 70 year time span starting in 1927; the reader has the chance to experience society at different points in Joss’ life and we can infer what the norm and day to day life would have been for Josephine. For example‚ in the 1930’s homosexuality was a taboo subject and racism was common whereas when the book was published in 1998 and now‚ homosexuality isn’t as much of a controversial topic and racism has declined. This rounded view of society is Kay’s desired

absorb moisture to prevent premature reaction. How Baking Soda works: When you mix together the baking soda‚ acidic ingredient and liquid you’ll get bubbles of carbon dioxide gas. Specifically‚ the baking soda (a base) reacts with the acid to give you carbon dioxide gas‚ water and salt. This works the same as the classic baking soda and vinegar volcano except instead of getting an eruption the carbon dioxide fizzes to puff up your baked goods. The reaction occurs as soon as the batter or dough

Zn(NO3)2 + 2 H2SO4 ? 2 ZnSO4 + 4 HNO3 4 FeSO4 + 2 H2SO4 ? 2 Fe2(SO4)3 + H2 These two reactions happen simultaneously. 2: 4 HNO3 ? 2 H2O + 3O2 + 2 NO The Nitric Acid decomposes in the intense heat produced by the high concentrate Sulphuric Acid used. 3: 2 Fe2(SO4)3 + 2 H2 + 4 NO ? 4 Fe.NO.SO4 + 2 H2SO4 The Fe.NO.SO4 forms a brown ring in the middle of the solution produced by the reaction‚ making it easy to identify the presence of nitrates in the water. 4.

we should learn electrochemistry! From submarines to space crafts to our daily life‚ electrochemistry is involved in many forms! We would study the following in this section: •Redox processes •Thermodynamics of redox reactions •Electrode potential •Chemical reaction taking place at electrodes •Electrochemical cells • Electrolytic cells • Galvanic cells • Voltaic cells •Hydrogen fuel cells 9 Brief history Luigi Galvani

Info and Causes Time and date was December 26‚ 2004‚ at 07:58:50 local time. The magnitude of the earthquake was 9.2 for 5 minutes. This was one of the most powerful earthquakes for 100 years. The fault ruptured on the subduction zone of the Indian (Eurasian) plate and the Sunda plate (Indonesian plate). The plates usually move 6.2cm per year. The epicentre was 20 kilometres deep under the sea(very shallow!)‚ 250km off the coast of Indonesia near the city of Banda Ache. The earthquake

Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina dissolved in cryolite. Cryolite
