Flashcard Content Overview

This flashcard set presents fundamentals for learning chemistry. You can test your memory of what metric prefixes like 'milli-' and 'centi-' mean. The cards review core principles of scientific notation and significant figures. They also offer practice problems for identifying how many significant figures are in a certain number. Students will also practice rounding calculation results based on significant figures in the problem. These flashcards also cover the meaning of various states of matter and how they are related.
