Document Summary

Both the reactant and the product side need equal amount of each atoms. Use whole number as coefficient to balance both side. Tips to balancing equation: balance compound first, balance hydrogen or oxygen next, balance monatomic element. Molecular equation is the full equation without any dissociation. Ex: ex: agno3(aq) + kcl (aq)------ agcl(s) + kno3(aq) Ionic equation is when the compound dissociate into ions. Ex: ag+ + no3- + k+ + cl- ------ agcl(s) + k+ + no3- Net ionic equation is the equation left after cancel the spectator. Acid-base reaction is the transfer of hydrogen ions (h+) in reactions. Strong acids completely dissolve in water ( hcl, hi, hbr, h2so4, hno3, hclo4) Acid donate protons ( h+) ( bronsted and arrhenius law) Base dissolve in water to produce oh- Bases are oh- donors ( arrhenius law) Bases are protons acceptor ( h+) ( bronsted law) Ex: nh3 + h2o ------- nh4+ + h2o.
