<u>Answer:</u> The complete ionic equation is written below.
<u>Explanation:</u>
Complete ionic equation is defined as the equation in which all the substances that are strong electrolyte are present in an aqueous are represented in the form of ions.
The balanced molecular equation for the reaction of lead (II) nitrate and potassium sulfate follows:
The complete ionic equation for the above equation is:
Hence, the complete ionic equation is written above.
A. Oxygen. Oxygen has an atomic mass of 16. The atomic mass of an atom is the combined weight o the protons and neutrons. Since Oxygen's atomic mass is 16, it has 8 protons and 8 neutrons.
