Time to test the limits! Young scientists make limiting reagent calculations and test their math using a virtual lab simulation. Using their knowledge of ionic compounds, they determine the limiting reagents and the excess compounds.

One of the most recognizable commercial melodies was written in 1977, and led to gastronomical relief around the world. Scholars use Alka Seltzer tablets to measure reactants and calculate the chemical equation for the reaction of NaHCO3...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...
