Answer 1

is this a multiple choice question?

Answer 2

Precipitation Reactions
Form: can be single or double displacement reactions (see above) that produce a solid
AB + C --> A (s) + CB or AB + C --> A + CB (s)
or, AB + CD --> AD + BC (s) or AB + CD --> AD (s) + BC

Example: 3 NaOH + Al --> 3 Na + Al(OH)3 (s) (single displacement precipitation)
NaCl + AgNO3 --> NaNO3 + AgCl (s) (double displacement precipitation)
