Example #1 (Trivial): CaCO3 + HCl
1. Iron + Hydrogen Chloride = Ferrous Chloride + Hydrogen Gas: Fe + HCl → FeCl2 + H2 2. Zinc + Hydrogen Chloride = Zinc Chloride + Hydrogen Gas: Zn + HCl → ZnCl2 + H2 1. CaO + H2O → Ca(OH)2
Example #2 (Simple): Na + H2O
1. Combustion of Methane and Oxygen: CH4 + O2 = CO2 + H2O

1. K4Fe(CN)6 + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + CO
Identify elements which occur in one compound on each side. This is very common (e.g. K, Mn, O and H in the prior example).Start with the one among those which has a big index (this will help to keep working with integers), and assign a variable, such as a. In the prior example, O has the largest index (4)Next, start determining other coefficients in terms of a: H2O has to be 4a (because of O), MnCl2 has to be 1a (because of Mn), and KCl has to be 1a (because of K).This eliminates the first three eq...One can continue by writing the equations now (and having a simpler problem to solve) or, in this particular case you could notice that to balance the Hydrogens between HCl and 4a H2O, you need 8a...How do you write chemical equations?Why do chemical equations need to be balanced?How do you balance an equation with fractions?How do you identify the type of reaction based on the chemical equation?Sodium Benzoate.

To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation. The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.
