Balance the following chemical equations including the physical states. a) C&HizOs C₂H-OH + CO₂ b) Fe+0: Fe:0₁ c) NH+ Cl → NHNHicl d) Na +H:O — NaOH +H;
Solution
Balanced chemical equation: A chemical equation in which the number of each type of atom is equal on the two sides of the equation. a)C₆H₁₂O₆→2C₂H₅OH + 2C0₂ This reaction is known as the reaction alcoholic fermentation of glucose. b)4Fe +30₂→2Fe₂O₃ In this reaction iron react with oxygen molecule to form iron oxide.c)NH₃ + Cl₂ → N₂H₄+NH₄Cl; (d) 8NH₃ +3Cl₂→N₂+6NH₄Cl. In this reaction 8 molecule of ammonia reacts with three molecule of chlorine tofrom nitrogen and six molecule of ammonium chloride.
