Title: why does each chemical reaction have many possible balanced equations? Post by: miche37 on Feb 15, 2013 AND....Of all the possible balanced equations, which is prefferred?
Title: why does each chemical reaction have many possible balanced equations? Post by: smokeypal23 on Feb 15, 2013 I'll explain with simple example-
2H2 + O2->2H2O now this means 2 moles of H2 react with 1 mole of O2 to form 2 moles of H2O. this can also be written as 4H2+O2->4H2O which means 4 moles of hydrogen on reaction with 2 moles of oxygen gives 4 moles of water.. the reaction in which there is no common number by which all reactants and product are divisible is the most common one!!! the given reaction is also sometimes written as- H2+1/2O2->H20 Title: why does each chemical reaction have many possible balanced equations? Post by: Smoores on Feb 15, 2013 Sorry but I cannot agree that "each chemical reaction has many possible balanced equations" . There is a specific balanced equation that describes how the reactants interact to produce the products. I am confident that most reactions ( probably close to 99% of reactions) are described by a unique specific reaction equation. This is the basics of chemistry.
