- decomposition reactions:
- single replacement rxns with nonmetals:
- Double replacement reactions:
- Single replacement rxns:
- one soluble and one insoluble:
- a 1) some metallic hydroxides when heated decompose to form a metal oxide + h20
2) some oxy-acids when heated decompose to form a metal oxide + h20
3) some metallic carbonates when heated decompose to form a metal oxide + carbon dioxide
4) some metallic chlorates when heated decompose to form a metal chloride + oxygen gas
5) most metallic osides are stable but few decompose when heated to form a metal + o gas
6) some compounds can be decomposed by electricity into their elements.
- b they have to do with the electromotive series. it arranges most reacted to least reacted.
- c will occur only if: both products are soluble, and it is a reaction between a acid and a base! memorize solubility rules!
- d only use the periodic table, no electromotive series! a nonmetal can replace a nonmetal below itself on the periodic table!
f, o, cl, br, i
- e have a reaction
5 Multiple choice questions
- this means electricity is used!
- have no reaction
- except for those in rule 1, carbonates, hydroxides, oxides, sulfides, and phosphates are insoluble.
- matter is neither created nor destroyed!
- binary compounds of group 17 other than F with metals are soluble except those of silver, mercury I, and lead
5 True/False questions
solubility rule 2: → except for those in rule 1, carbonates, hydroxides, oxides, sulfides, and phosphates are insoluble.
Diatomic elements: → a+bc= b+ac
on the left is the: → products
solubility rule 4: → all sulfates are soluble except those of barium, strontium, lead, calcium, silver, and mercury I.
both insoluble: → a+b=ab
