 | Term | Definition |
| |
Synthesis Rxns |
metel + non-metel ----> one ionic compound (w/ no charge) |
| |
Make the bold choice |
For synthesis and single replacement rxns if a reactant has more than one possible charge you make the bold choice |
| |
Decomposition Rxns |
one reactant ---> 2 or more products (break down reactant into each element) |
| |
Exceptions to decomposion |
ClO3 (chlorate); CO3 (carbonate); HCO3 (bicarbonate) |
| |
Decomposition exception ClO3 (chlorate) |
Any compound w/ ClO3 (chlorate) ---> Chloride + O2 ((x-chlorate ---> x-chloride + O2) |
| |
Decomposion exception CO3 (carbonate) |
Any compound w/ CO3 (carbonate) ---> O2 (oxide) + CO2 (carbon dioxide) ((x-carbonate --> x-oxide + carbon dioxide)) |
| |
Decomposition exception HCO3 (bicarbonate) |
Any compound w/ HCO3 (bicarbonate) --> O2 (oxide) + CO2 (carbon dioxide) + H2O (water) ((x-bicarbonate ---> x-oxide + CO2 + H2O)) |
| |
Combustion Reaction |
Any compound of C and H or C,H,O react with O2 to form CO2 and H20; CxHyOz (hydrocarbons) + O2 --> CO2 (carbon dioxide) + H2O (Water) --- any thing that reacts with 02 is a combustion reaction |
| |
Hints when balancing combustion equaitons |
Coefficient for the hydrocarbon will be either 1 or 2 |
| |
Single replacement reactions |
element + ionic compound --> new element + new ionic compound OR element + ionic compound --> No Reaction (SURBURBAN SQUARE MEDAPHORE), use the hot or not sheet and make the bold choice |
| |
Double Replacement Reaction |
Double Swap Surburban Square Medaphore. ionic compound (aqueus) + ionic compound (aquesus) --> new ionic compound + new ionic compound. Determine state of products and then if both are aquesus stop but if either is not then balance and make ionic and net ionic equations |
| |
Making ionic equations |
1) break down all aqueus compounds into ions (with # and charge) 2) leave solid, gas, liquid compounds alone |
| |
Making net ionic equations |
Cancel out like-terms on sides of reactants and products (ionic equation without spectator ions) |
| |
Making the bold choice |
Make the bold choice for single replacement reactions and synthesis reactioins |
| |
Order of writing compounds |
Write compounds with positive ion first then negative ion |
| |
H2CO3 (Carbonic Acid) turns into what? |
H2CO3 (carbonic acid) turns into H20 (liquid) + CO2 (gas) ---water and carbonate |
