Law of the Conservation of Energy (N) - Answer - Energy cannot be created or destroyed and is conserved in chemical reactions. Exothermic Reaction (N) - Answer - Transfers energy to the surroundings so that the temperature of the surroundings increases. Include combustion, many oxidation reactions and neutralisations. Endothermic Reaction (N) - Answer - Takes in energy from the surroundings, decreasing the temperature of the surroundings. Includes thermal decompositions, the reaction of ci...

SCI 228 ANSWER KEY END OF CHAPTER QUESTIONS / REVIEW EXERCISES Chapter 1 Introduction to Human Anatomy and Physiology Part A 1. Briefly describe the early development of knowledge about the human body. Our earliest ancestors probably became curious about the body during illnesses and injuries. At these times, they visited shamans who relied on superstition and magic. Throughout early time, this curiosity lead to discoveries of the healing powers of certain herbs and potions, especially to t...

These are notes created in my final year of sixth form to summarise in detail and concisely all the information I needed for my final exams. This contains all the information needed for the topic with full equations for half reactions and cell notations with interpretations of the results.

I got an A* in my chemistry A-Level using the notes that I have uploaded and I am currently studying chemistry at the University of Birmingham. These revision notes include detail on the composition of an electrochemical cell, electrochemical cell equations, representing electrochemical cells, standard hydrogen electrode, predicting the direction of redox reactions using the relevant half-reactions and E/V values, kinetics of electrochemical cells, non-rechargeable cells, and rechargeable cells.
