2014 Fall Final Exam Honors Chemistry List of important topics
The final exam is all multiple choice. It must be completed in one sitting (no extra time!) unless previously cleared with your teacher.
You will be allowed to use a calculator with the me
Identifying and determining ions: An ion is an atom or molecule in which the total number of electrons is not equal to the total
number of protons, causing it to have a positive or negative charge.
To determine the charge an atom will form
Elements/Compounds/Mixtures/Pure substances Density calculation and concept
Density = (mass) / (volume)
Methods of separation (c, c, d, d, e, f)
Centrifuge: spinning really fast to separate liquids of different densities
Chromatography: separation o
Law of definite proportions chemical compounds ALWAYS contain the exact same proportions of elements by mass (or moles)
Law of constant composition All samples of a compound will contain the same elements in the same proportions
Arrangement of the per
Law of conservation of mass In a chemical reaction, the mass of the reactants = the mass of the products. No mass is lost
during a reaction.
Scientific method basics The scientific method is a dynamic process used to answer questions about our physica
