What are the coefficients for the following reaction when it is properly balanced? ? potassium iodide +? lead (ii) acetate lead (ii) iodide +-potassium acetate 3,2,2,1 1,1,2,2 none of these

none of the above

Explanation:

It should be 2,1,1,2 to give a balanced chemical reaction

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

sry but any answer choices
