## What is Balance Chemical Equation?

Ever needed to balance a chemical equation but it is too difficult to do it by hand? This application will help you to balance the equation in the blink of an eye. You just need to type the reactants and the products and click the button 'balance'. 

• Sample Equations 

Fe +  Cl2 =  FeCl3  

KMnO4 +  HCl =  KCl + MnCl2 + H2O + Cl2

C6H5COOH +  O2 =   CO2 +  H2O

H3PO4 + Ca(OH)2  =  CaHPO4.2H2O

Cu + CO2 + O2 + H2O =  CuCO3.Cu(OH)2

• You just need to use lowercase letters to indicate chemical element symbols. 

Fe -> fe 

KMnO4 -> kmno4 

FeCl3 -> fecl3

CaHPO4.2H2O -> cahpo4.2h2o

• You can use X symbol for unspecified element 

X + O2 = XO2
X + HCl = XCl3 + H2
