10 ON TIPS NOTES Note taking is a skill that we use in many walks of life : at school, university and in the world of work. However, accurate note making requires a thorough understanding of concepts. We, at Oswaal, have tried to encapsulate all the chapters from the given syllabus into the following ON TIPS NOTES. These notes will not only facilitate better understanding of concepts, but will also ensure that the each and every concept is taken up and every chapter is covered in totality. So go ahead and use these to your advantage go get the OSWAAL ADVANTAGE!! CHAPTER 1 : Chemical Reactions and Equations Key Points and Concepts A complete chemical equation represents the reactants, products, conditions of reaction and their physical states symbolically. Oxidation : loss of electrons. Reduction : gain of electrons. Rust is mainly hydrated iron (III) oxide, Fe 2 O 3.xH 2 O. Important Equations Types of Reactions S. No. Name & Definition 1. In a combination reaction, two or more reactants combine to give single product 2. In a decomposition reaction, a single reactant breaks down into two or more simpler products 3. When decomposition reaction is carried out by heating, it is called thermal decomposition reaction 4. When decomposition reaction is carried out in the presence of sunlight, the process is called photochemical decomposition 5. Electrolysis : When decomposition reaction is carried out with the help of electric current, the process is called electrolysis. 6. In a displacement reaction, a more reactive element displaces a less reactive element from a compound Example CaO(s) + H 2 O(l) Ca(OH) 2 (aq) (Quick lime) (Slaked lime) 2Pb(NO 3 ) Heat 2 2PbO(s) + 4NO 2 (g) + O 2 (g) (Lead nitrate) (Lead oxide) (Nitrogen dioxide) (Oxygen) CaCO 3 (s) (Calcium carbonate) 2AgBr(s) Heat CaO(s) + CO 2 (g) (Quick lime) Sunlight 2Ag(s) + Br 2 (g) (Silver bromide) (Silver) (Bromine) 2H 2 O(l) electric current 2H 2 (g) + O 2 (g) (Water) (Hydrogen gas) (Oxygen gas) Fe(s) + CuSO 4 (aq) FeSO 4 (aq) + Cu(s) (Iron) (Copper sulphate) (Iron sulphate) (Copper)
