Chapter 7 Flashcards
Physical state
(l) (g) (s)
Melcular style equation
Compounds are writing by their neutral chemical formula.
All reactants are specified in the physical state they appear in.
Arrow is used
The products are added after the arrow (including physical state)
Good place to start balancing
Metals
Double displacement
(AB+CD->AD+CB
Synthesis
A+B -> AB
Decomposition
AB->A+B
Single displacement
A+BC->AC+B
Molecular equation
Complete, neutral, and smallest form
Ionic equations
Metal and non metal
Shown
Kl(aq) -> K+(aq)+I-aq)
Shows charges
Complete ionic equation
Shows all ions explicitly
Combination of other two
2K+(aq) + 2I-(aq) + Pb2+(aq) + 2NO3-(aq) -> 2K+(aq) + 2NO3-(aq) + PbI2(s)
The net ionic
Complete ionic without spectator ions
Spectator ions
Ions that do not undergo chemical change
Precipitation reactions
Reactions that form a solid, called precipitate, made upon mixing two aqueous solutions.
Acid-base reactions (neutralization)
Acid + base =
Water + Salt
Gas evolution
Aqueous factions that form a gas and aqueous product
