Comparison between Galvanic and Electrolytic Cell
Comparison between galvanic and electrolytic cell table Students tend to get mixed up between the two types of electrochemical cells. This table will illustrate the comparison between galvanic and electrolytic cell. A useful acronym, P.A.N.I.C. for electrolytic cell polarity (Positive is Anode Negative is Cathode). Then just remember polarity is reversed for galvanic cell. If you found this useful, share it with your friends! Back to Home of Best H2 Chemistry Tuition ...

Physical Chemistry Calculations – Be Aware Where Errors Occur
Physical Chemistry Calculations Physical Chemistry - Recently i was revising acid-base equilibrium with one of my students and i realised she has trouble getting the right answer even though the procedure is correct. We went through the process and every step was conceptually correct. Then i got her to show me how she calculated on her GC, i saw the workings and it was right. But when she pressed "=", the answer came out wrong! Boy, was i puzzled. We went through the steps carefully again and still we arrived at the same outcome. Finally, after i queried her on one of the steps, we both realised what's wrong. She did not use brackets to sequence the operations, thus the ...

Born Haber Level Diagram
Born Haber Level Diagram Born Haber Level Diagram Always start your cycle at datum line, i.e. at zero enthalpy. Tip: You may combine the ionisation energies for Fe or for other metals. Multiple electron affinities can also be combined. Take note that for energy level diagram, you will have to show the ionized electrons from Fe. When you use bond energy instead of enthalpy of atomisation, you will need to multiply by the correct coefficient. Lastly, don't forget to put your state symbols! 🙂 Hope this has been useful for you, if you wish to learn how to draw the diagram using energy cycle, go here.

Born Haber Cycle
Born Haber Cycle Born Haber Cycle Diagram Using the acronym F.A.I.L. where F stands for enthalpy change of formation of the ionic compound, A stands for atomisation of the constituent elements and I stands for ionisation of cation and anion and L stands for Lattice Energy. We have four major components  and this energy cycle is easy to draw with no worries about which species having a higher energy level. There is no need to include electrons as they are immediately used to form the anion. Hope this has been useful to you! Share it with your friends if it has helped you 🙂 Back to Home of Leading H2 Chemistry Tuition Centre ...

Organic Novel Questions Book
Organic Novel Questions Book By the time this post is published, hopefully we would have finished the proofreading and sent for printing. Distribution to the bookstores might take a month or so but i hope to make it in time for the 2019 A levels Examination. This is my second book and i hope it will cater to a different group of students. If you recall, my first book was to meet the demand from private candidates who needed practical worksheets for practice. This Organic Novel Questions Book hopes to address the needs of students who are competent doing the standard questions and want to stretch themselves.  This doesn't mean that average students shouldn't buy the book. It only means ...
