Objectives of Chemical Reactions and Stoichiometry

Essential Question: Do you believe that? (theory explains observations)
Enduring Understanding: ?????

The student should be able to:(bolded number are MA Framework Standard numbers)

1. Classify chemical reactions as Synthesis (Combination), Decomposition, Single Displacement (Replacement), Double Displacement (Replacement) and Combustion. [5.2, Pg.72]

2. Explain the significance of the coefficients of a balanced chemical reaction (number of particles, moles, and volume)

3. Balance chemical equations (by applying the law of conservation of mass and constant/definite proportion)[5.1, Pg.72]

4. Calculate the mass-to-mass stoichiometry for a chemical reaction. [5.5, Pg.72]

5. Calculate percent yield in a chemical reaction [5.6, Pg.72]

<b>From previous objective, not gotten to on last test. Now on this test.
3. Understand the difference between an Empirical Formula (EF) and Molecular Formula (MF) and how it relates to the subscripts of the chemical formula.

4. Calculate EFand MF. This include determining EF from mass data, percent composition info, and MF from mass data, percent composition and EF data.

5. Predicting Products of:

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

Determine the net ionic reaction from a complete chemical reactions (especially for a single and double replacement reaction)[7.7]

Updated 2006 - (5.6) Calculate percent yield in a chemical reaction (also in Limiting Reactant & Redox section)

Things needed to be memorized

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

Things that can be in the folder

Reaction Stoichiometry directions and/or figure
Activity series table (for single replacement reactions)
Solubility Table (for one type of Double Replacement reactions)
