It can only be converted from one form to another.The Law of Conservation of Matter and EnergyThe combined amount of matter and energy available in the universe is fixed.Chemistry – A molecular view of matterDalton’s atomic theory1) 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
