An unknown solid compound containing Pb2+ ion was mixed with 15 mL of 2.0 M HNO3. The mixture bubbled profusely. After complete reaction, it was found that 0.020 moles of CO2 were produced and the original solid was completely consumed.
a) What is the chemical formula of the unknown solid?
b) Write a balanced net ionic equation for this reaction.
c) Calculate the mass of the original unknown solid.
