SC3 Obtain, evaluate, and communicate information about how the Law of Conservation of Matter is used to determine chemical composition in compounds and chemical reactions.

SC3.a Use mathematics and computational thinking to balance chemical reactions (i.e., synthesis, decomposition, single replacement, double replacement, and combustion) and construct an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

• I can state the law of conservation of matter.

• I can use coefficients to balance equations to support the Law of Conservation of Matter

• I can identify the types of chemical reactions.

• I can classify a reaction as synthesis, decomposition, single replacement, double replacement, or combustion.

• I can use coefficients to provide evidence that a balanced equation supports the Law of Conservation of Matter in different chemical reactions.

• I can explain how the Law of Conservation of Mass relates to the formation of products in a chemical reaction.

• I can use mathematics and computational thinking to balance chemical reactions and construct an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

SC3.b Plan and carry out an investigation to determine that a new chemical has been formed by identifying indicators of a chemical reaction (e.g., precipitate formation, gas evolution, color change, water production, and changes in energy to the system).

• I can recall the types of chemical reactions.

• I can identify indicators of a chemical reaction in an experiment.

• I can classify different chemical equation by type of chemical reaction.

• I can relate the observation of a chemical change and the production of a new substance to a balanced chemical equation.

• I can use the information in a chemical equation to write the complete and net ionic reaction equations. [HONORS only]
