<center><b>Objectives of Chemical Reactions and Stoichiometry</b></center><br> <br> <b>Essential Question: Do you believe that? (theory explains observations)</b><br> <i>Enduring Understanding: ?????</i><br> <br> <br> The student should be able to:(bolded number are MA Framework Standard numbers)<br> 1. Classify chemical reactions as Synthesis (Combination), Decomposition, Single Displacement (Replacement), Double Displacement (Replacement) and Combustion. <b>[http://www.doe.mass.edu/frameworks/scitech/1006.pdf 5.2, Pg.72]</b><br> 2. Explain the significance of the coefficients of a balanced chemical reaction (number of particles, moles, and volume)<br> 3. Balance chemical equations (by applying the law of conservation of mass and constant/definite proportion)<b>([http://www.doe.mass.edu/frameworks/scitech/1006.pdf 5.1, Pg.72]</b><br> 4. Calculate the mass-to-mass stoichiometry for a chemical reaction. <b>[http://www.doe.mass.edu/frameworks/scitech/1006.pdf 5.5, Pg.72]</b><br> <br> 5. Calculate percent yield in a chemical reaction <b>[http://www.doe.mass.edu/frameworks/scitech/1006.pdf 5.6, Pg.72]</b><br> <br> <b>All information after line to end of page is Not on Test or Midyear</b><br> -----------------------<br> <b>From previous objective, not gotten to on last test. Now on this test.</b><br> <i>3. Understand the difference between an Empirical Formula (<nowiki>EF</nowiki>) and Molecular Formula (<nowiki>MF</nowiki>) and how it relates to the subscripts of the chemical formula.</i><br> <i>4. Calculate <nowiki>EF</nowiki>and <nowiki>MF</nowiki>. This include determining <nowiki>EF</nowiki> from mass data, percent composition info, and <nowiki>MF</nowiki> from mass data, percent composition and EF data.</i><br> 5. Predicting Products of:<br> *Decomposition, Synthesis and Combustion reactions(assume complete combustion, no incomplete combustion) *Synthesis reactions *Single Replacement reactions *Double Replacement reactions 6. Explain the difference between a complete chemical reaction and a net ionic reaction<br> *Determine the net ionic reaction from a complete chemical reactions (especially for a single and double replacement reaction)<b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_117.html 7.7]</b> <br> <b>Updated 2006 - (5.6) Calculate percent yield in a chemical reaction (also in Limiting Reactant & Redox section)</b><br> <i><u>Things needed to be memorized</u></i><br> *Seven diatomic elements (again, carryover from last test) *Phases of all elements at room temperature (get info from Periodic Table) *Five different types of chemical reactions *What products you get if you react oxygen with C,H,N,S *Everything you memorized from Chemical Naming & Mole Concept Chapter <br> <i><u>Things that can be in the folder</u></i><br> *Reaction Stoichiometry directions and/or figure *Activity series table (for single replacement reactions) *Solubility Table (for one type of Double Replacement reactions) <br>
