Matter Most basic building block. Must have mass and volume Elements Simplest form of matter, can't decompose any further Molecules Two or more atoms "linked" together Compounds Mixes of two or more elements bonded together Sig Fig.- x & / As many as the least number Sig Fig.- + & - As many as the least behind the decimal point Law of Definite Composition Components in a compound always have the same ratio by mass Law of Multiple Proportions Ratios of elements that combine to m...

BTEC APPLIED SCIENCE LAB REPORT ON OXIDATION AND REDUCTION. FND04: FURTHER CHEMISTRY FOR BIOSCIENCES - LAB REPORT Oxidation and Reduction (REDOX) Reactions Introduction Oxidation-reduction reactions, otherwise known as redox reactions, are fundamentally a process that involves a transfer of electrons. Oxidation can be defined as loss of electrons and reduction as gain of electrons. Therefore, oxidation results in an increase in oxidation number and reduction a decrease in oxidation numb...

Edexcel iGCSE Chemistry, question and answer with rated solution Experiment for Diffusion? 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour le...

BIOL275 Exam 3|Graded A+ Highly exothermic redox reactions lead to high levels of released energy. This wouldn't be compatible with life if too much energy is released at once, because this would be wasteful and potentially damaging to the cell. If the cartoon above represents a molecular reaction taking place between common biological molecules in a living cell, why would we expect that the change in energy level of electrons would NOT be highly exothermic? Living functions in the cell depe...

CHEM120 Week 5 Concepts: Redox and Organic Chemistry – Download For Revision And Score An A+ OXIDATION-REDUCTION Reduction and oxidation are intertwined concepts that are important to understand ing some of the most important chemical reactions in the human body. In this lesson, we will explore the relationship between these terms and the how to identify what chemicals in a reduction/oxidation reaction (redox reaction) are playing which parts. 1. Redox reactions involve a transfer of: ▪ Nucl...
