6.1Word Equations216Word equations are written in a particular format. They represent the combinations of various elements and their reactions.Left side represents the substances initially presentThe right side represents the all the products created at the end of the reactionReactant 1 + reactant 2 Product 1 +product 2Some common chemical reactions 1.RustingIron+oxygeniron(III)oxide2.Copper wire placed in sivernitrateCopper +silver nitrate silver+copper(II)nitrate3.Zinc metal added to a hydrochloric acid solutionZinc+hydrochloric acidhydrogen +zinc chloride4.A chemical test for hydrogenHydrogen+oxygenwater vapourExamine the following word equation:Propane+oxygencarbon dioxide +watera.List the reactantspropane o2b.List the productsco2 waterc.What is the purpose of the arrow in the equation.Try writing the word equations for the following reactions:
1.CaCl2 and Na2SO4 react to form CaSO4 and NaClCalcium chloride + sodium sulfate Calcium sulfate + sodium chloride2.BaCO3 reacts when heated to produce BaO and CO2Barium carbonate barium oxide + carbon dioxide3.AgNO3 reacts with KCl to produce AgCl and KNO3Silver nitrate + potassium chloride silver chloride + potassium nitrateWrite the word equation to represent the following chemical reactions:a.Carbon dioxide and water are produced in human cell respiration. The reactants are sugar and an important gas that humans need to surviveC6H12O6+O2 C2O + H2OSugar (glucose) + oxygen carbon dioxide + waterb.Stalactites form in caves when calcium bicarbonatereacts to formcalcium carbonate, water and carbon dioxide gas.Ca2CO3 CaCO3 + H2O + C2O
