1. write the charges for each element/ion in this question. Treat NO3 as a singer thing with a charge of -1.

[ ] [ -1] [ ] [ ] [ -1]
Pb(NO3)2 + KI → PbI2 + 2KNO3

2. what did you notice about the charges for each element or ion in this reaction

3. Would you consider this a redid reaction? why or why not explain.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the answer is c i took the test
