The loss of any language means a contraction‚ reduction and impoverishment of the sum total of the reservoir of human thought and knowledge as expressible through language. To what extent do you agree with this? As globalization takes place‚ languages spoken by the majority became lingua franca of different regions. English for example as its most widely spread across the entire world‚ is spoken by 360 to 400 million as their first language and 470 million to more than 1 billion as their second

safety feature in vehicles. Sodium azide‚ potassium nitrate and silicon dioxide have been used in one design of airbag. [Source: www.hilalairbag.net] Sodium azide‚ a toxic compound‚ undergoes the following decomposition reaction under certain conditions. 2NaN 3 (s) → 2Na (s) + 3N 2 (g) Two students looked at data in a simulated computer-based experiment to determine the volume of nitrogen generated in an airbag. (a) Sodium azide involves ionic bonding‚ and

REACTION PAPER It is said that effective teacher will use both assessment and evaluation regularly to improve student learning and to guide instruction. Indeed‚ both have pivotal roles in the teaching-learning process yet‚ somehow they do differ in many ways. Assessment and evaluation measure whether or not learning and/or learning objectives are being met. One could look at assessment and evaluation as the journey (assessment) versus the snapshot (evaluation). (Sue Watson‚ 2009) Assessment requires

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials‚ formation constant

INTRODUCTION – OBJECTIVES In this first experiment‚ we will perform 8 chemical reactions and 1 flame test in order to determine 2 things : a) firstly‚ we can know whether a reaction occurred or not. To complete our mission‚ we need to observe carefully some signs of chemical reaction’s appearance such as the change in color of solution
