Question

gasahol is a fuel that contains ethanol (C2H6O(g)), which burns in oxygen(O2) to give two gases, carbon dioxide and water. express yoir answer as a chemical equation.

Answer 1

Solution : The equation the question of the is reaction given in minol) Hot oa CO2 + H₂O gasabol commenct with onygen to give Carbon dionide and water This is not a balanced chemical equation. we have to Balance the chemical equation. . C2H60+02 02 + H2o. To balance a chemical equation the number of atoms or ions of the reactans and The number attoms ar ions of the procluct are must be equal. Sacha, Reaction is called in chemical equation Balanced chemical equation Consider the equation, Ca Heo to2 CO2 + H2O No of atoms of reactants H=6 0 =1+2=3 No of atoms of product c=1 H= 2 0=3 Fust we have to Balance Carbon atoms - C2H60+ Oo (@coa + Hool R c=2 H=6 0 = 3 c=2 H = 2 0 = 5 o

Ajantha Nent we have to balance bydrogen atoms Ca Hoo+02 - 2002 + ③H₂O C = 2 H=6 c=2 H=6 L z3 0 = 7 The Carbon atoms and on both side are equal. Hydrogen atoms. Nent we have to Balance onygen atoms. - CHGO+ ② 0 2 10 + 3 H₂O Sir C= H= 6 0 = 7 inch C3Q H=6 -7 0 The number of atoms of the product is equal to the Number of atoms of the Reactant. This is a Balanced chemical equation. Hence, The Balanced chemical equation of the Reaction of ethanol with ony gen is, Ca HGO + 302 > 2002 + 3 H₂O
