Tittel Balancing Chemical Equations - Inquiry based Introduction
Beskrivelse Learning Goals - Students will be able to: •Describe what “reactants” and “products” in a chemical equation mean. •Explain the importance of knowing the difference between “coefficients” and “subscripts”. •Use pictures and calculations to show how the number of atoms for each product or reactant is found. •Identify the relationship between “reactants” and “products” atoms. •Balance a chemical equation using the relationships identified. •Given a chemical equation, draw molecular representations of the reaction and explain how the representations were derived. •Given a molecular drawing of a chemical reaction, write the equation and explain how the symbols were derived.
