Document Summary

Chemistry: deals with composition, structure, and reactions of matter. Matter has mass and occupies space: mass measures quantity of matter, weight result of gravitational attraction between matter. Weight and mass are not the same. Composition what matter is made of and how much of each component is present: e(cid:454)pressed (cid:271)(cid:455) . # of atoms: macroscopic can be seen and weighed, submicroscopic level number and types of atoms.

Qualitative = ethanol consists of carbon, hydrogen and oxygen. Structure arrangement of components and how they are bonded: different arrangements of same combination of components = isomers, structures rotate freely, dashed lines = behind dark triangles = forward. Exothermic reaction produces energy over a long period of time. Experiment (record observations) numerical + observational: careful recordings and analysis of data. Controlled conditions so we pinpoint what is causing another thing to happen: reproducible.
