I will go over 5 questions from each worksheet. Assigned questions: Sheet 7 and sheet 8 from the first handout for this chapter. Please see below for helpful hints with Properties Assignment which is due tomorrow.

Chemistry 121-Today you will do a pair assignment on enthalpy and heat loss or gain from the booklets. You will receive a handout that has problems for this unit on it, as well as the table that I mentioned last class.

SPECIAL NOTE TO CHEM 112 students: you will find that is good to use the formula to help decide if something is acid(hydrogen on front), Base( hydroxide on end, ammonia or ammonium), ionic(metal attached to nonmetal) or molecular(nonmetals attached to each other). [|MAJOR Properties Assignment.doc] [|Table Of Empirical Data For AcidsBasesIonicMolecular.doc] From WIKIPEDIA: The symbols in parentheses (in subscript below each species) indicate the physical state of each reactant or product. PLEASE NOTE CHEM 112 Students-->One of your classmates emailed the following questions regarding the assignment. Please read the document below with the answers to the excellent questions that the person asked. [|Good Questions regarding MAJOR ASSIGNMENT.docx]
 * **(s)** means solid --> like table salt or sucrose
 * **(l)** means liquid --> like water or hydrogen peroxide
 * **(g)** means gas --> like propane or ammonia
 * **(aq)** means aqueous solution (i.e. dissolved in water) --> like hdrochloric acid or hyponitrous acid
