found in the lab manual Chapter 1 The foundations of Chemistry Matter and Energy Matter is anything that has mass and occupies space Mass is a measure of the quantity of matter in a sample of any material Energy is defined as the capacity to do work or to transfer heat mechanical light electrical heat energy Kinetic energy energy that matter possesses due to its motion Potential energy is the energy an object possesses because of its position condition or composition Exothermic energy is released to the surroundings usually as heat energy something will get hot Endothermic absorb energy from their surroundings something will get cold The Law of Conservation of Matter There is no observable change in the quantity of matter during a chemical reaction or during a physical change The Law of Conservation of Energy Energy cannot be created or destroyed in a chemical reaction or in a physical change It can only be converted from one form to another The Law of Conservation of Matter and Energy The combined amount of matter and energy available in the universe is fixed Chemistry A molecular view of matter Dalton s atomic theory 1 An element is composed of extremely small indivisible particles called atoms 2 All atoms of a given element have identical properties which differ from those of other elements 3 Atoms cannot be created destroyed or transformed into atoms of another element 4 Compounds are formed when atoms of different elements combine with each other in small whole number ratios 5 The relative numbers and kinds of atoms are constant in a given compound Some Definitions An atom is the smallest particle of an element that maintains its chemical identity through all chemical and physical changes Fundamental particles are the basic building blocks of atoms they consist of electrons protons and neutrons A molecule is the smallest particle of an element or compound that can have a stable independent existence 19 Atomic number of protons in the nucleus look at periodic table Diatomic molecules H2 N2 O2 F2 Cl2 Br2 I2 have to memorize these NOW States of matter Matter can be classified into 3 stages solid liquid gas Solid substance is rigid and has definite shape Liquid substance confined to a given volume liquid assumes shape of container hard to compress liquid molecules close together Gas much less dense than liquids and solids compressed easily consist mainly of empty space molecules are quite far apart Fig 1 7 p 10 States of matter Solid Liquid Gas rigidity Expansion compressibi on heating lity Rigid Flows and assumes shape of
