Question

Write a balanced equation for the reaction of copper with silver nitrate. According to the balanced equation, what is the mole ratio of silver produced to copper reacted?

_ mol Ag produced : _mol Cu created

Answer 1

Balanced equation: Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Mole ratio: 2 mol Ag produced : 1 mol Cu used

Step-by-step explanation:

• A balanced equation is an equation that has equal number of atoms of each element on both sides of the equation.
• It ensures the chemical equation obeys the law of conservation of mass.

In this case;

• The balanced chemical equation for the reaction between copper and silver nitrate is;

Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

• It is an example of a single replacement reaction.
• From the equation 1 mole of copper reacts to generate 2 moles of silver.
• Therefore; the mole ratio is 2 mol Ag produced : 1 mol Cu used
