This page is an extra set of resources to help you learn and review the summer assignment material.
Measurement, Significant Figures & Dimensional Analysis
Measurements in Chemistry
Accuracy & Precision
Determination and Analysis of Error
Using Significant Figures to Communicate Precision
Converting Units using Dimensional Analysis
Classification of Matter & Properties
Matter is a substance or mixture of substances
Matter can be classified as an element, compound or mixture
The composition of a pure substance is determined by the ratio of atoms present
Atoms & Ions
An atom is the smallest unit an element
Atoms can be identified by its electron distribution and energy
Isotopes
Isotopes of an element have the same number of protons and different number of neutrons.
The mass spectrum of an element determines the identity of isotopes for an element and the relative abundances of each isotope.
Writing Chemical Formulas & Naming Compounds
Chemical formulas identify substances by their unique combination of atoms
The formula for a substance is the fixed ratio of atoms present
Substances use systematic (IUPAC or stock system) of naming.
Chemical Reactions & Balanced Equations
Chemical reactions result in chemical changes of substances
Chemical reactions follow the Law of Conservation of Mass & Energy
Balanced chemical equations show conservation of atoms and therefore conservation of mass.
Chemical reactions may be synthesis, decomposition, single replacement, double replacement or combustion.
How to handle the math in ap chemistry
Melissa Maribel's instructional videos for college-level chemistry are excellent. I highly recommend that you subscribe to or bookmark her channel and refer to the topics that are giving you some trouble. this playlist has great resources for general strategies that will help you complete math problems.
