8.1 molecular equation for the reaction; it shows the complete formulas of all reactants and products
Ions such as these, which do not participate directly in a reaction in solution, are called spectator ions

net ionic equation, includes only those components that are directly involved in the reaction

a. Molecular equation:
NaCl(aq) _ AgN O3 (aq) n AgCl(s) _ NaN O3 (aq)
Complete ionic equation:
N a_ (aq) _ C l_ (aq) _ A g_ (aq) _ N O 3 _ (aq) n
AgCl(s) _ N a_ (aq) _ N O 3 _ (aq)
Net ionic equation:
C l_ (aq) _ A g_ (aq) n AgCl(s)
b. Molecular equation:
3KOH(aq) _ Fe(N O 3)3 (aq) n Fe(OH )3 (s) _ 3KN O3 (aq)
Complete ionic equation:
3 K_ (aq) _ 3O H_ (aq) _ F e3_ (aq) _ 3N O3 _ (aq) n
Fe(OH )3 (s) _ 3 K_ (aq) _ 3N O 3 _ (aq)
Net ionic equation:
3O H_ (aq) _ F e3_ (aq) n Fe(OH )

3.5 We can produce a charged entity, called an ion, by taking a neutral atom and adding or removing one or more electrons

Ionic compound A compound that results when a metal reacts with a nonmetal to form cations and anions

A positive ion, called a cation is produced when one or more electrons are lost from a neutral atom. Questions 1-5 1) That there is more than just earth wind water and fire but they didn’t realize that until like the 1700-1800s so it's only been around for a couple hundred years.

2) ore testing and refining, metalworking, production of gunpowder, ink, dyes, paints, cosmetics, leather tanning, ceramics, glass
