Document Summary
Lecture 4: chapter 4 stoichiometry of chemical reactions: outline, 4. 1 writing and balancing chemical equations, 4. 2 classifying chemical reactions, 4. 3 reaction stoichiometry, 4. 4: reaction yields, 4. 5: quantitative chemical analysis. (aq: complete ionic equation- explicitly showing all dissolved ions, ca2+ (aq) + 2cl- + 2ag+(aq) + 2no3. Chemistry 1111: net ionic equation- equation that includes only the species that are actually involved in the reaction, 2 chemical species are present in identical form on both sides of the arrow, ca2+ (aq) These ions are called spectator ions- ions that appear on both sides of the. Spectator ions are required to maintain charge neutrality and are neither chemically nor physically changed by the process: elimination of the spectator ions results in a net ionic equation, ag+(aq) + cl-(aq) agcl(s) 4. 2 classifying chemical reactions: precipitation reaction- dissolved substances react to form one (or more) solid products. The polarity of water results from electron dist(cid:396)i(cid:271)utio(cid:374)s withi(cid:374) the (cid:373)ole(cid:272)ule.
