Answer the following questions about molecular-formula equationsand net-ionic equations.
Part 1:
Molecular Formula Equation: Lead (II) nitrate is combined withsodium sulfate. Write the formulas of the starting materials andpredict the products. Balance the Molecular Formula Equation, andenter the sum of the coefficients below (include any impliedones):
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 remaintogether? Rewrite the equation with everything written as theyappear in the reaction. How many total UNIQUE substances are inyour 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 andsubscripts of your original balanced equation, write the totalionic equation, and sum up all coefficients (including impliedones). Enter your sum below:
Part 4:
Net Ionic Equation: Part 1: Finally, cancel any substances thatremain unchanged from the beginning to the end of your TOTAL IONICEQUATION. How many UNIQUE substances remain? Enter the numberbelow:
Part 5:
Net Ionic Equation: Part 2: Balance the equation determined inpart 4. Add up the coefficients (including any implied ones), andenter the sum below.
