Respuesta :
The sum of coefficients for all reactants and products of given reaction is 12.
[tex]CuBr_{2} + H_{3}PO_{4}[/tex]⇨ [tex]Cu_{3} (PO_{4})_{2} + HBr[/tex]
For finding coefficients each molecules in reactant and product, first we have to balanced the given chemical equation.
What is balanced chemical equation?
The chemical equation in which number of atoms for each elements and total charges is same in both side, reactant as well as product in a reaction.
Example: Let the unbalanced chemical equation is,
[tex]CuBr_{2} + H_{3}PO_{4}[/tex]⇨ [tex]Cu_{3} (PO_{4})_{2} + HBr[/tex]
So, the balanced chemical equation become.
[tex]3CuBr_{2} + 2H_{3}PO_{4}[/tex] ⇨ [tex]Cu_{3} (PO_{4})_{2} +6 HBr[/tex]
Reactant Product
The number placed prior to the each molecules is called coefficient of reactant and product.
So, the total coefficient for reactant and product are 3 + 2 + 1 + 6 = 12.
