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. Recognize Synthesis,Decomposition,Single Replacement,Double Replacement (including Neutralization), and Combustion given a chemical reaction ([5.2])
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)([5.1](5.1))
4. Calculate stoichiometric problems including([5.5](5.5)):
(Two Mole Wheels and the bridge between them, Molar Ratio.)
- moles of known substance - moles of unknown susbtance
- mass of known substance -mass of unknown susbtance
- mass of known substance -volume of unknown susbtance
- mass of known substance -particles of unknown susbtance
- volume of known substance -volume of unknown susbtance
- volume of known substance -mass of unknown susbtance
- volume of known substance -particles of unknown susbtance
- particles of known substance -mass of unknown susbtance
- particles of known substance -volumes of unknown susbtance
- particles of known substance -particles of unknown susbtance
All information after line to end of page is Not on Test or Midyear
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)
