Document Summary
Chemistry: the science that seeks to understand the behavior of matter by studying the behavior of atoms and molecules. 1. 1: atoms and molecules: atoms: submicroscopic particles. Fundamental building blocks of matter: molecules: two or more atoms attached together geometrically. Different shapes and patterns: properties of substances depend on atoms and molecules that compose the substances. Carbon monoxide gas depends on carbon monoxide molecules: rights size, shape, chemical properties. 1. 2: the scientific approach to knowledge: scientific knowledge is based on observation and experiment. Qualitative: noting or describing how a process happens. Quantitative: measuring or quantifying something about the process: observations often lead scientists to formulate a hypothesis. Scientific law: a brief statement that summarizes past observations and predicts future ones. Law of conservation of mass: in a chemical reaction, matter is neither created nor destroyed. : one or more well-established hypotheses may form the basis for a scientific theory.
