Question

Answer the following questions about molecular-formula equations and net-ionic equations.

Part 1:

Molecular Formula Equation: Lead (II) nitrate is combined with sodium sulfate. Write the formulas of the starting materials and predict the products. Balance the Molecular Formula Equation, and enter the sum of the coefficients below (include any implied ones):

Part 2:

Total Ionic Equation: Part 1: In the reaction in part one, determine how each substance appears in the reaction. For example, does the substance appear as dissociated ions? Do the ions remain together? Rewrite the equation with everything written as they appear in the reaction. How many total UNIQUE substances are in your equation.

For example: Na+(aq) + Cl-(aq) + Ag+(aq) + NO3-(aq) → Na+(aq) + NO3-(aq) + AgCl(s)

This reaction has 7 unique substances.

Part 3:

Total Ionic Equation: Part 2: using the coefficients and subscripts of your original balanced equation, write the total ionic equation, and sum up all coefficients (including implied ones). Enter your sum below:

Part 4:

Net Ionic Equation: Part 1: Finally, cancel any substances that remain unchanged from the beginning to the end of your TOTAL IONIC EQUATION. How many UNIQUE substances remain? Enter the number below:

Part 5:

Net Ionic Equation: Part 2: Balance the equation determined in part 4. Add up the coefficients (including any implied ones), and enter the sum below.
