Aim
To understand the fundamentals of atomic structure, chemical bonding, periodic tableandits application in engineering problems.
Objective
Observing and explaining the reasons of engineering chemistry related problems. Applying the basics of chemistry knowledge in explaining challenges related to periodic table. Observing and explaining the use and rationale of certain chemicals in industries.
A. Knowledge and understanding of the topic
This assignment will give a better chance to show understanding of atomic structure and its relation with properties of materials.
Students will get chance to apply knowledge for solving future challenges of periodic table. It will test their understanding of basics of periodic table.
B. Application and analysis of the topic
This is the way in which studentanalyse/ examine the factual information related with atomic structure and chemical bonding and how they interpret this information to add value to theanswer in the form of conclusions, solutions, and recommendations.
C. The structure in terms of logic and coherence
Submissions should have a clear start and a clear end. Information within submissions should also be logical and well grouped. Report structure, Abstract, Introduction & Referencing, Result Analysis, and Conclusion& Future works.
D. The use of relevant work examples and/or examples gained from further reading
Suggestions for further reading are contained within the course work and indicated at the end of the course work. These reading lists are not exhaustive and candidates are encouraged toread further and reference at the end of the course work using Harvard style of referencing.
Tasks
Task 1:
Hydrogen bond is a weak bond in terms of bond energy but very important in deciding physical and chemical properties of few important molecules.
Discuss three examples of molecules having hydrogen bonding and their important properties. Answer must include scientific information about:
a. Effect of hydrogen bonding on physical and chemical properties of those molecules.
b. How the property of molecules change if Hydrogen bond is not present in the molecule.
c. Structure, data and technical explanations for observations. (Word limit 750 words)
Task 2:
Position of an element in modern periodic table is important factor in deciding its physical and chemical properties like reactivity of compounds, nature of bonding etc. Considering this observation answer following questions:
i. Suggest which block and group elements preferably make ionic bonding and covalent bonding. Justify answer with proper example and data. (Word limit 500 words)
ii. Discuss how the discovery of modern periodic table has made the study of physical and chemical properties of elements easy and scientific?
(Word limit 500 words)
Task 3: Doing experiments based on theoretical knowledge, consolidates the understanding. Students have to do following experiments in lab and record all findings, observations and results in given log sheet.
1 To learn the basic laboratory techniques
2 To prepare the standard solution of oxalic acid
3 To determine the amount of sodium hydroxide in the given solution
4 To determine the amount of sulphuric acid in the given solution
5 To compute a relation between millivolt and pH of given solutions
6 To estimate the amount of barium as barium sulphate in the given solution
