DefinitionsCurrent LectureChapter 1-A Chemical WorldChemistry is a part of our everyday lives and not many people see that as true because they don’t actually know that chemistry is everything. Chemistry shapes the economical, political andsocial choices in our everyday lives.Most people think of chemistry as dangerous, toxic, poison or polluting. But in turn chemistry is all about explaining what things are made of, their properties and how things change and interact.Chemical Free SunscreenIs it possible to have chemical free anything?

Observations involve measuring or observing some aspect of nature. Hypotheses are tentative interpretations of the observations.These notes represent a detailed interpretation of the professor’s lecture.
