For Chemical Naming and Mole Concept
Each student will be able to:
- Differentiate between molecular and ionic compounds (cpd) on the basis of:
- material that composes the cpd
- bonding (including how valence electrons are interacting)
- the name for the chemical formula of each type
- the name of the smallest unit of the cpd
- Using only the chemical name, how you differentiate between the different types of cpds
- Using only the chemical formula, how you differentiate between the different types of cpds
- Determine the chemical formula from the chemical name for ionic cpds and molecular cpds.
- Determine the chemical name from the chemical formula for ionic cpds and molecular cpds.
- Calculate the molar mass of ionic and molecular cpds
- Understand how to use the MOLE WHEEL (in your folder)
- Be able to use three Mole Equation. Calculate the moles from knowledge of the grams, # of particles, and volume (of a gas @STP)of elements, ionic cpds, or molecular cpds AND VISA VERSA I call them One Step Problems
- Calculate any grams, number of particles or volume (of a gas @STP) from any of the other information I call them Two Step Problems
- Calculate the number of components in a compound if you have the number of the smallest unit of this compound and other related questions.
- Empirical Formulas (EF)and Molecular Formulas (MF)
- Be able to explain the difference between EF and MFin terms of what they represent.
- Be able to explain how EF and MF related to chemial formulas of ionic cpds and molecular cpds (called Molecular Formulas).
- Calculate Percent Composition from both actual mass of elements in a cpd or from a simple chemical formula.
- Calculate the Empirical Formula from actual mass or mass percent of the elements that make up the cpd.
- Calculate the Molecular Formula from the Empirical Formula and the molar mass of the molecular cpd.
- Calculate the Molecular Formula from actual mass or mass percent of the elements in the cpd and the molar mass of the molecular cpd.
- Things needed to be memorized
- All polyatomic ions
- All cations with more than one charge
- All ions that can be determined directly from the Period Table
- Silver, Zinc and Nickel ions
- All prefixes for naming molecular cpds
