Document Summary
Limiing reagents: quaniies mixed do not follow stoichiometric raio, smaller number of reactants, that means you will have some of a substance let over and use all of the limiing reagent, always check for a limiing reagent. Reacion yields: most real reacions produce less product than equaions predict, % yield = actual yield/theoreical yield = percent yield. Soluions: homogenous mixture, solvent is major component, solute is minor component, aqueous soluions water as solvent, soluions have variable concentraion . Ions and ionic compounds: ions = atoms or groups of atoms with an electrical charge, caion= posiive charge, anion= negaive charge. Ionic compounds: held by coulombs force, combine anions and caions, ionic compounds are crystalline solids with high meling points, many dissolve in water, overall soluion is neutral, net ionic equaions omit spectator ions .
