Question

Balance. Pb+cucl2=pbcl2+cu

Answer 1

Answer:

pb + cucl2= pbcl2 +cu

Explanation:

this equations is already balanced so there is need to change

Answer 2

The balabnced chemical equation will be $Pb+CuCl_2\rightarrow PbCl_2+Cu$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balabnced chemical equation will be :

$Pb+CuCl_2\rightarrow PbCl_2+Cu$

The number of atoms of each element Pb, Cu and Cl are equal on both sides.
