Document Summary
The properties of matter are determined by the properties of molecules and atoms. They are very similar in the molecular context, and differ significantly in their chemical properties. The 2nd oxygen prevents co2 from binding to the oxygen-carrying site in hemoglobin, making it far less toxic blood by fitting into hemoglobin cavities (normally reserved for oxygen) Breathing air with >0. 04%of co by volume can lead to unconsciousness and even death. Breathing air with >10% of co2 can be hazardous. Used to bleach hair to strip off hair colour. Atoms- the submicroscopic particles that constitute the fundamental building blocks of ordinary matter. Molecules-2 or more atoms joined in a specific geometrical arrangement. Central goal of chemistry- the science that seeks to understand the behaviour of matter by studying the behaviour of atoms (atoms that have lost or gained electrons) and molecules. Scientific knowledge is empirical based on observation and experiment. Qualitative noting or describing how a process happens or.
