Question

What are the coefficients of the complete ionic reaction that occurs when aqueous solutions of lead(II)

acetate [Pb(C₂H302)2] and calcium chloride (CaCl₂) are combined?
Pb²+ + C₂H3O₂ + Ca²+ + Cl
------> PbCl₂ + Ca2+ + C₂H3O2
O 1, 2, 1, 2, 1, 1, 2
2, 1, 1, 2, 1, 1, 2
O 1, 1, 2, 2, 1, 1, 2
O 2, 2, 1, 2, 1, 1, 2

Answer 1

The coefficients of the complete ionic reaction are 1, 2, 1, 2, 1, 1, 2.

Step-by-step explanation:

The coefficients of the complete ionic reaction that occurs when aqueous solutions of lead(II) acetate [Pb(C₂H302)2] and calcium chloride (CaCl₂) are combined are:

• Pb²+ + C₂H3O₂ + Ca²+ + Cl → PbCl₂ + Ca2+ + C₂H3O2
• Coefficients: 1, 2, 1, 2, 1, 1, 2

So, the correct answer is 1, 2, 1, 2, 1, 1, 2.
