State the Law of Conservation of Matter. How does the Law of Conservation of Matter figure into the simulation? Use how the masses of reactants and products were related after 10 g of calcium nitrate were added to 40 grams of sodium carbonate in the first example. Be specific and use actual values to make your point. Generalize this to all chemical reactions. Was the total mass of reactants always equal to the total mass of products or was the mass of the reactants that reacted equal to the total mass of products formed?
Why did adding more calcium nitrate produce more products to a point, then stop having an effect?
What is the limiting reactant before the stoichiometric amount of calcium nitrate was added? What is the limiting reactant after the stoichiometric amount of calcium nitrate was added? How can you tell from the simulation?
Approximately how many grams of calcium nitrate were required to react totally with 40.0 g of sodium carbonate? How many grams of product were formed at that point? Do your answers appear to obey the Law of Conservation of Matter?
Was it easy to tell when you added the stoichiometric amount of calcium nitrate?
What is the balanced equation? How did you determine it?
