Classifying Matter

Classifying Matter:

I can distinguish between physical and chemical changes in matter evident by my ability to

• Cite evidence for the occurrence of a chemical reaction vs. a change in physical properties alone

I can use symbolic representations and mathematical calculations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction evident by my ability to

• Explain how mass is conserved during physical and chemical changes in lab situations
• Identify reactants, products, and the symbols used in chemical equations
• Explain the meaning of coefficients and subscripts and use coefficients and subscripts to count atoms involved in a chemical reaction
• Recognize whether the number of atoms of the reactants and products in a chemical equation are balanced
• Illustrate how to balance chemical reactions by changing coefficients

I can classify matter based on its characteristics evident by my ability to

• Distinguish between elements, compounds, homogeneous mixtures, and heterogeneous mixtures based on the physical and chemical properties of the substances
• Use particle diagrams to show the differences between mixtures, compounds and elements
• Measure a compounds solubility based on temperature of the solvent; Construct and interpret data in a solubility graph

Vocabulary: Physical & chemical properties, physical & chemical changes, reactants, products, subscript, coefficient, diatomic elements, law of conservation of mass, balancing chemical equations , Homogeneous & Heterogeneous matter, pure substance, element, compound, homogeneous mixture, heterogeneous mixture, solution, colloid, suspension, solvent, solute, saturated, concentration, solubility
