Journal: Prove It!Journal: Prove It! The illustration shows the mixing of two colorless aqueous solutions (lead nitrate and potassium iodide) in a sealed flask to form a yellow precipitate (lead iodide) and a colorless solution (potassium nitrate). Record your answers to the following questions:• What is meant by the phrase, “conservation of mass?”• How would you prove that mass is conserved in this reaction?• The equation that represents this reaction is Pb(NO3)2(aq) + 2 KI(aq) PbI2(s) + 2 KNO3(aq). In what ways does this equation show conservation of mass?
