Answer:
Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)
Step-by-step explanation:
- To balance a chemical equation of a reaction we put appropriate coefficients on the reactants and products to make the number of atoms of each element is equal on both sides of the equation.
- Balancing of chemical equations is a try and error method that ensures chemical equations obey the law of conservation of mass.
In this case;
- The reaction between copper and silver nitrate is;
Cu(s) + AgNO₃(aq) → Cu(NO₃)₂(aq) + Ag(s)
- To balance the equation, we put coefficients 1, 2, 1, 2 in the unbalanced equation.
- Therefore, the balanced equation will be;
Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)
