Document Summary
Inertness: susceptibility to reaction: whether or not you react is close tired to the way the electrons are distributed in the nuclei. Chemical change: matter undergoing a change in composition: types of chemical change, precipitation reaction, combustion reaction, electrochemical reaction: makes all of the batteries possible and is used in the. What temperature really means which is motion of matter. Temperature is a relative measurement of temperature: kelvin made the temperature scale in the idea that temperature is the motion of matter and that the atoms move back and forth. When you jump between unit scales you get an irrational number back so scientist went with things that you can divide with powers of 10. Chapter 2: atomic theory of matter: atomic theory of matter. John dalton (1766-1844): he was a numerate chemist because he worked on gases mostly but dalton is famous for the atomic theory of matter.
