The balanced equation reaction :
2Cu+(aq) + PbO2(s) + SO42–(aq) + 4H+ -----------> PbSO4(s) + 2 Cu2+(aq) + 2H2O
A balanced equation is an equation for a chemical reaction in which the range of atoms for every detail in the reaction and the full charge is identical for both the reactants and the products. In other phrases, the mass and the fee are balanced in each aspect of the reaction.
A balanced equation happens while the variety of the atoms involved inside the reactants side is identical to the variety of atoms in the goods facet. in this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to provide ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.
A chemical equation is the symbolic representation of a chemical reaction inside the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities.
Eo = Eored - Eo oxd
= 1.69 - 0.153
= 1.54 V
Eocell is positive so the reaction is spontaneous.
