Embark on a molecular adventure where elements dance and nothing is lost, as we explore the transformative world of chemical reactions and the conservation of matter with these enlightening learning outcomes: • Recognize that atoms are conserved during a chemical reaction. • Use concrete everyday experiences (such as making sandwiches) to describe the what a limiting reactant means in chemical reactions. • Identify the limiting reactant in a chemical reaction. • Predict the products and leftovers after reaction, based on the quantities of reactants and ratios of molecules in the balanced chemical equation. • Predict the initial amounts of reactants given the amount of products and leftovers using the concept of limiting reactant. • Translate from symbolic (chemical formula) to molecular (pictorial) representations of matter.
