I created this activity to help students in physical science and/or in first year chemistry better understand the components of a chemical equation. In this lesson, students have to identify: the reactants and products in a forward and reverse reactions, the coefficient and subscript number for a given molecule, the number of molecules in an equation with a coefficient greater than one, the number of molecule species in an equation that contain subscripts, what the subscript indicates the number of, what is affected by the coefficient number, which labeled reactants and products by symbol are aqueous, liquid, solid, or gas in physical state, which component is replaced in a single replacement reaction from the outside metal, and the number of a specified product formed from a specified number of a given reactant. Students also are given the opportunity to classify reactions and assess whether the reactions are balanced to honor the Law of Conservation of Mass.
There are two complex reactions in chemical equation form students analyze in this activity. I scripted 13-14 questions for each reaction for analysis. Two pages of color-coated digitalized answer key are provided.
I included an extra first student version page without the inset strategic hint boxes.
