Document Summary
Introduction: chemistry and chemicals is an integral part of life. H2o, 11. 19% h and 88. 81% o- fixed composition vs h2o2. Sample of matter displays physc. prop. without change of composition: phys. Change: change in sample without change of composition. F there is chem. rex, it is chem. prop. Exp: gold is used for making jeleler, coins. Matter is made of atoms (smallest unit cell!! Compounds are comprised of two or more elements. Molecules are the smallest units of compounds: all material object whether living or inanimate are made up of chemicals, chemistry is a science of manipulating chemical compounds which deal with the composition and properties of the matter. The scientific method: science-method that scientist use to gain knowledge, knowledge use to explain natural phenomena also to do some prediction, firstly, methods were related with some assumptions/ then certain conclusions come: deduction(not enough). Next progression: no initial assumption/rather careful observation/enough observation generalization-natural law:
