Okay, write out the chemcial forumula for all of the compounds. For single displacement reactions, you'll need a reactivity series. For double displacement you need an ionization chart... (or wait is that what it's called?
) But I think these arn't meant to be difficult.
Synthesis is reactions where smaller molecuels are used to build a bigger molecule:
A + B --> AB
Decomp. is when a bigger molecule is broke down into smaller ones:
AB --> A + B
Single displacement are reactions where one element(usually a non metal) is displaced from a compound by another element (another non metal) Where AB + C --> AC + B
Double Displacement is when the compounds "switch partners"
AB + CD --> AD + CB
ie:
1. magnesium bromide + chlorine ---->> magnesium chloride + bromine
MgBr2 + Cl2 ---->> MgCl2 + Br2 is a single displacement reaction because chlorien displaced the bromine
3. Silver Nitrate + zinc chloride
AgNO3 + ZnCl2 --> AgCl + Zn(NO3)2 is a double displacement rxn because they switched partners, and so on. Get it?
ETA:
but it's called the solubility chart.
YES! that's what's that thing's called solubility rules!
The single displacement rxns thing is called the reactivity series.
