How balance chemical equation |
|
Answer» take the number of atom on the reactant side and the no of atom on product side and the check them out by trial and error method ORu can check out the algebraic formula, I am explaining with a simple equation H2 + O2 -----> H2ONow put some variable in front of each element, aH2 + bO2 -----> cH2O2a = 2c and 2b = cTake either of a,b,c as 1I am taking a as 1Therefore, 2 = 2c => c =1Now put c in 2b=c =>b =1/2Put the value of a b and c in equation 1H +1/2 O2 -----> 1H2O (suffix can\'t be in fraction there fore try to remove fraction) (1H2 + 1/2 O2 ----> 1H2O) * 2=2H2 + O2 ----> 2H20hence ur equation is balanced Y |
