ECON Batch 2013 LIVE created on 08/06/2013

Team Questions Session (18th March)

4. The concerns of acid rain vary across the globe. Many countries in North America and Europe have websites dealing with acid rain. Either search to locate one(“Canada,acid rain”) or use these links to website in Canada , the UK or Europe. What are the issues in the country you selected? Does the acid rain deposition originate outside the borders of the country?

Eastern Canada

  • Acid rain affects lakes, forest, soils and wildlife populations and buildings
  • Many of the waters and soil lack natural alkalinity and hence, cannot neutralize acid naturally
  • Most of Canada landscape consist of hard rock and cannot neutralize the effects of acid rain

Implications to our society

Quotation-James-Hillman-control-society-talking-power-people-Meetville-Quotes-102386

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

This unit studies how the chemical industry applies key principles of physical chemistry in order to turn research ideas into profitable products without harming the environment.

An increasing share of future energy needs will be met by technologies now in the research or development phase.

Public and private research into technologies that could improve—or even completely change—our energy situation has been active for years. This tells unit explains how energy affects our quality of life in now and in the future.

Why is it Important?

Implications to society

Introduction :
Chemistry and energy has become increasingly important and relevant in our daily life. Its uses and applications have established a strong implication and relationship with our society. Its presence in life is distinctive and huge.

Explanation :
In chemistry, Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction or, to transform other chemical substances.
The products of chemistry save energy by improving energy efficiency in our homes, offices and factories and by making cars and packaging more lightweight.
Chemistry innovations also enable the sustainable technologies that are revolutionizing the way we generate and store energy—solar cells, wind turbines, rechargeable batteries and more.

Chemical Concepts (Unit 4)

Introduction:
This course allows one to have a rough idea on the implications of chemistry on the society through illustrating on the various interaction man has with chemistry. This better allow us to relate to chemistry in our daily life.

Explanation:

Lewis structures and shapes

  • Lewis structures,” which combine multiple atoms using electron dot diagrams, and show bonding electrons as well as lone pairs of electrons. It’s very important to know how to draw both electron dot symbols and diagrams, as well as Lewis structures, because you can get a lot of relevant information from these structures, including electron location, number and types of bonds, and geometric structure.

Valence Shell Electron Pair Repulsion Theory

  • This theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.

IR Spectrum and interaction with molecule

  • Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. This can be analyzed in three ways by measuring absorption, emission and reflection. The main use of this technique is in organic and inorganic chemistry. It is used by chemists to determine functional groups in molecules. IR Spectroscopy measures the vibrations of atoms, and based on this it is possible to determine the functional groups. Generally, stronger bonds and light atoms will vibrate at a high stretching frequency (wave number).

3 laws of thermodynamics

Uses of energy

  • We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. If projections are correct, we’re going to keep needing more. Global consumption is expected to increase by 44% over the next 2 decades.
