Introduce limiting and excess reactants using an analogy of ice cream and ice cream cones
Developing understanding is a series of resources that encourage learners to connect their thinking at the macroscopic, sub-microscopic and symbolic levels. This worksheet will promote understanding of limiting and excess reactants as learners consider how observations (macroscopic understanding), state symbols in a chemical equation (symbolic understanding) and the number of reacting atoms and molecules (sub-microscopic understanding) can be used to determine the limiting reactant and excess reactants.
