AgNo3+Cu—>Cu(No3)2+Ag

2AgNO3+Cu—>Cu(NO3)2+2Ag

Explanation:

AgNo3+Cu—>Cu(No3)2+Ag

The chemical equation is not balanced.

We need to balance the equation. This means that the number of moles of atoms or radicals present at the start of the reaction is same as the number of moles of atoms or radicals present in the product.

Atoms and radicals present in the reactants are;

1 mole of Ag

1 mole of (NO3)^- radicals

1 mole of Cu

Atoms and radicals present in the products are

1 mole of Cu

2 moles of (NO3) ^-

1 mole of Ag

The equation is not balanced because there is only one mole of (NO3) ^- in the reactant side and 2 moles in the product side

2AgNO3+Cu—>Cu(NO3)2+2Ag

Now the equation is balanced.
