Examples: H2 + O2 = H2O will become H2 + O2 = 2H2O
Fe + Cl2 = FeCl3 will become 2 Fe + 3 Cl2 = 2 FeCl3
KMnO4 + HCl = KCl + MnCl2 + H2O + Cl2 become 2 KMnO4 + 16 HCl = 2 KCl + 2 MnCl2 + 8 H2O + 5 Cl2

all complicated equations can be balanced by our tool easily. Dont break your head to balance equations any more. no worries. no thinking. just enter the equation and its balanced. it takes care of moles, weight, molar mass, coefficient. Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.Chemical balance for equations in stoichiometry in chemistry

Periodic table added. All 118 from H to Uuo(118). All elements of periodic table can be seen.
