Balanced Chemical Equations?
How would I write balanced chemical equations for these?
:s i'm confused
1. The decomposition reaction of hydrogen sulfide
2. The single displacement reaction of copper(ll) & silver nitrate.
3. The synthesis reaction of sodium & fluorine.
4. The double displacement reaction of aluminum sulfate & calcium hydroxide.
also i would appreciate it if you explained how you did it.

1. a decomposition reaction starts with 1 molecule & produces more that one material , materials usually which are very common:
H2S --> H2 & S
2. The single displacement reaction uses a single element to replace a similar element that is in a compound:
Cu(s) & 2 AgNO3 --> Cu(NO3)2 & 2 Ag (s)
3. The synthesis reaction usually combines 2 materials into producing one
2 Na & F2 --> 2 NaF
4. The double displacement reaction starts with two molecules made of ions which swap negative ions:
1Al2(SO4)3 & 3Ca(OH)2 --> 2Al(OH)3 & 3CaSO4
