The equation that shows conservation of both mass and charge is:
(4) Ni + Pb²⁺ → Ni²⁺ + Pb
What do conservation of mass and conservation of charge stand for?
- Conservation of mass: there is the same mass, i.e. same number of atoms, in the reactants and in the products.
- Conservation of charge: there is the same electrical charge in the reactants and in the products.
Which equation shows conservation of both mass and charge?
(1) Cl₂ + Br → Cl⁻ + Br
No, the equation does not show conservation of mass nor charge.
(2) Cu + 2 Ag⁺ → Cu²⁺ + Ag
