Document Summary

Chemistry origins from 3 overlapping conditions: alchemy, medicine and technology. Debate of phlogiston in combustion, lavoisier discovered oxygen and metal oxides and proved. Convert to appropriate units before solving a problem. > temp is how hot or cold one object is relative to the other. (k=c +273. 1) >heat is the energy which flows from the object with the higher temp to one that has a lower one. Matter can be classified based on composition: elements, compounds, and mixtures. Elements and compounds are substances. (substance= matter whose composition is fixed) Elements consist of only one atom, compounds consist of 2 or more elements that are chemically bonded, and mixtures consist of two or more substances. The law of conservation of mass: mass is conserved because matter cannot be created or destroyed. Law of definite composition: no matter what its source, a particular compound of the same element in the same parts (fractions) by mass.
