Introduce students to stoichiometry and mole ratios with the reaction of copper and silver nitrate! Students will watch as beautiful silver crystals are formed on the copper wire, then determine the moles of silver formed and moles of copper reacted to calculate the mole ratio. Using this data, they will write the balanced chemical equation for the reaction, and determine the limiting reactant and their percent yield. Kit contains enough materials for 15 groups of students. Teacher’s Manual and Student Study Guide Copymasters are included.
