Chemical Reactions and Equations-Notes

Iron Oxygen Ferric oxide. Features of a chemical equation:. The arrow head points towards the products and indicates the direction of the reaction. Skeletal chemical equation: A chemical equation which simply represents the symbols and formulas of reactants and products taking part in the reaction is known as skeletal chemical equation for a reaction. Combination Reaction : Two or more reactant combine to form a single product. Decomposition Reaction : A single compound decomposes or break down to give two or moresimpler substances. Oxidation Reaction: In oxidation reaction, addition of oxygen or removal of hydrogen or loss of electron takes place.

Revision is one of the most important aspects of learning as it helps you to remember facts, figures, and topics that you have covered earlier. Students are always advised to summarize whatever they have learned as Revision Notes. A physical change occurs when a substance changes but no new substance is formed. The chemical composition remains the same. Examples: Crushing of bottles, cutting of paper, etc.
