10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

Abstract: The reaction used to determine the experimental rate law of is 2I-(aq) + H2O2(aq) I2(aq) + 2H2O2(l). The rate law determined experimentally is rate= k[I-]1.017[H2O2]0.927. Additionally by performing essentially the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Also‚ from graphs the activation energy was determined to be 33.3 kJ/mol. INTRODUCTION: The rate of a chemical reaction often depends

Ki Hadjar Dewantara (as cited in Sumarsam‚ 2003‚ p. 168) argued that “put the Javanese art spectacle as an obligated curriculum in Taman Siswa is the most important thing to do.” Actually‚ the writer agrees with Ki Hadjar Dewantara’s argument. By putting the Javanese art spectacle as an obligated curriculum‚ then the students can learn and understand about

Culture of transgender as sex worker: a world inside a world Introduction: Gender is often confused with sex. Sex generally refers to anatomy and biology whereas gender refers to qualities and behaviours society expects from a female or a male. These roles are learned‚ change over time and vary enormously across and within cultures[1]. There are not too many people in the world who can say they’ve been both a mother and a father.

When ionic solids dissolve‚ they divide to give their positive and negative ions that make up the solids. These ions become hydrates and have the same relative proportions when in solution and when solid. The more the solid dissolves‚ the more the ion’s concentration increases. This increase and build-up allows for the reverse reaction to occur. In this phase of the reaction the ions crystallise out in order for the reaction to have a greater chance of occurring. Eventually the rate of
