ENERGY AND MATTER IN CHEMICAL CHANGE
ENERGY AND MATTER IN CHEMICAL CHANGE
Chemical changes involve energy and transformations of matter. A knowledge of the underlying structure of matter and the basic chemical species is important in understanding chemical changes. As students explore the properties of molecular and ionic compounds, including acids and bases, they begin to appreciate the need for a classification scheme and a system of nomenclature. Students classify, name compounds and write balanced chemical equations to represent chemical changes. As well, students are introduced to the law of conservation of mass and the mole concept.
Particle Model of Matter
WHMIS symbols, pure substances, mixtures and solutions
Reactants, Products, Conservation of Mass, Periodic Table, Elements, Compounds, Atomic Theory, Chemical Nomenclature.
Acids and Bases
How has knowledge of the structure of matter led to other scientific advancements?
How do elements combine?
Can these combinations be classified and the products be predicted and quantified?
Why do scientists classify chemical change, follow guidelines for nomenclature and represent chemical change with equations?
