Basic Biochemistry Webquest (2013) Basic Chemistry Part 1: Why Do Atoms React? Google Search 1. What is an atom? An atom is the basic unit of a chemical element. 2. What is an element? An element is a substance that is made entirely from one type of atom. 3. What makes an atom unstable (reactive)? The binding energy not being strong enough makes an atom unstable (reactive). 4. Why do atoms react with other atoms? Atoms react with other atoms to gain or lose electrons to fill their outer

CHARACTERISTICS AND DATA TYPES OF VISUAL BASIC INTRODUCTION The characteristics and data types of Visual Basic elucidated its advantages and disadvantages. Visual Basic is a popular event-driven visual programming system from Microsoft Corporation for Microsoft Windows (Morley‚ 2008). It is an Integrated Development Environment (IDE)‚ which uses a Graphical User Interface (GUI) to create and modify code (Capron‚ 2004). It enables Rapid Application Development (RAD) of graphical user interface

again. This causes the reverse reaction rate to increase this time. This process continues to happen until the rate of the forward reaction and the backward reaction becomes equal. When this happens‚ chemical equilibrium is achieved by the reaction system. Whenever equilibrium is achieved‚ at any given time‚ both reactants and products will be present at any given point in time since their concentrations remain constant. Given a reaction‚ aA + bB ⇌ cC + dD kf[A]a[B]b = kr[C]c[D]d kfkr

Microorganisms: * Small living organisms; there are 3 types * Bacteria – ecoli‚ salmonella * Fungi – mushrooms‚ athletes foot * Virus – influenza (flu)‚ HIV * When they enter our body‚ they multiply and release toxins / harmful chemicals into our blood * They duplicate every 20 minutes * Physical barriers: eyelashes prevent MO’s from entering through our eyes‚ nasal hairs reduce them‚ skin is a barrier to them (although they can enter through cuts)‚ chemicals in tears

special occasions like independence day. The excitement produced by fireworks like ‚ brightening the night sky and plunging it with vivid displays of colour and insignificant‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an important role in creating the vivid colours we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides
