CHE 115 GENERAL CHEMISTRY CHAPTER 1 numerate AND MEASUREMENT CONTENTS INTRODUCTION 2) PROPERTIES AND CHANGES OF emergence 3) SIGNIFICANT FIGURES 4) ACCURACY VERSUS PRECISION 1) INTRODUCTION chemistry is the study of matter and the changes it undergoes. a. b. c. i. ii. cause: some(prenominal)thing that has mass and occupies space centre of attention: form of matter that has a definite small-arm and unequivocal properties Mixture: combination of 2 or more sums in which the internalitys retain their distinct identities equivalent: composition same passim Heterogeneous : composition non uniform d. e. fragment: made of the same loving of atom; canonical aggregate that can not be broken by any physical and chemical meat to simpler tendernesss Compound: containing dickens or more elements CLASSIFICATION OF MATTER The watch of Chemistry THE THREE STATES OF MATTER bungle shoot a line: Loose structure SOLID: set(p) structure solid liquidness smooth: Less Rigid Structure PROPERTIES AND CHANGES OF MATTER personal Properties: o Can be discover without changing a union into another substance. boiling point, density, mass, volume. chemical Properties: o Can only be observed when a substance is changed into another substance. Flammability, corrosiveness, reactivity with acid.

intense Properties: o Independent of the measuring of the substance that is present. Density, boiling point, color. Extensive Properties: o qualified upon the amount of the substance present. Mass, volume, energy. CHANGES OF MATTER physiologic Changes: ? does not alter the composition or identicalness of a substance. Changes of state, temperature, volume, etc. Chemical Changes: ? alters the composition or identity of the substance(s) involved. Combustion, oxidation, decomposition, etc. UNITS OF MEASUREMENT SI UNIT  outside(a) System of Units (SI) METRIC SYSTEM  vividness: 1 cm3 = (1 x 10-2 m)3 = 1 x 10-6 m3 1 dm3 = (1 x 10-1 m)3 = 1 x 10-3 m3 1...If you necessitate to get a encompassing essay, order it on our website: Ordercustompaper.com
