| State the three main rules of synthesis | A) nonmetalic oxide+water=acid B) metalic oxide+nonmetalic oxide=salt C) metalic oxide+water=element(base) |
| four main rules for single-replacement | A) metal will replace a less reactive metal in an aqueous salt solution B)metal replaces hydrogen in water to form the base+H2(gas) C)metal+acid will produce a salt+hydrogen gas D) halogen will replace a halogen in a salt solution if it is more reactive |
| Three main rules for Decomposition | A) metalic chlorates when heated will yield salt+oxygen B) metalic carbonates will yield metalic oxide+CO2 C)metalic hydroxides will yield metalic oxide+water |
| Some oxides when heated will yield | nonmetalic oxide+water~H2CO3->H2O+CO2(gas)/2HNO3->H20+N2O5 |
| A binary acid (when heated) will yield | No Reaction |
| some metalic oxides (when heated) will yield | the lesser oxide+O2(gas) or metal+O2(gas)***if higher valence is used->metalic oxide+O2***if lower valence is used->metal+O2 |
| Electrolysis... | breaks compounds down into respective ions/NaCl(aq)->Na+Cl |
| 2H2O->(elec) | 2H2+O2 |
| Using complete combusion: | always add O2 to reactant side/H20 is always a product+CO2(gas) |
| Incomplete combustion: | CO(gas) is added to H2O |
| In double displacement... | the positive ions switch places in an aqueous solution |
| Reversible if... | both products are aqueous |
| Not reversible if... | 1) H2O is a product 2) a gas is released 3) precipitate is present (in products) |
