Phet Sims Reactants Products And Leftovers Answer Key Pdf
If you're studying chemistry, you know how important it is to understand the different types of chemical reactions. One of the best ways to learn about these reactions is through the use of simulations. PhET Sims (PhET stands for Physics Education Technology) are a set of free online simulations created by the University of Colorado Boulder that allow students to interact with virtual labs and experiment with different chemical reactions.
What are reactants?
In chemistry, reactants are the starting materials in a chemical reaction. They are the substances that are combined to create a new product. For example, in the reaction between hydrogen gas and oxygen gas to form water, hydrogen and oxygen are the reactants. The reactants are written on the left side of a chemical equation.
What are products?
Products are the substances that are created as a result of a chemical reaction. Continuing with the example of the reaction between hydrogen gas and oxygen gas to form water, water is the product. The products are written on the right side of a chemical equation.
What are leftovers?
In some chemical reactions, not all of the reactants are used up in the reaction. The remaining reactants are called leftovers. The amount of leftovers depends on the stoichiometry of the reaction, or the relationship between the amounts of the reactants and products. For example, if there is an excess of one reactant, there will be leftovers of that reactant.
Using PhET Sims to Understand Reactants, Products, and Leftovers
PhET Sims offer a great way to visualize and better understand chemical reactions. One of the best simulations to use to learn about reactants, products, and leftovers is "Reactants, Products, and Leftovers." In this simulation, students can experiment with different amounts of reactants and see how they affect the amount of the product that is produced.
The simulation allows you to choose from a number of different reactions, including the reaction between hydrogen and oxygen to form water, the reaction between sodium and chlorine to form salt, and the reaction between magnesium and hydrochloric acid to form magnesium chloride and hydrogen gas.
Once you have chosen a reaction, you can adjust the amount of each reactant and see how it affects the amount of the product that is produced. You can also see what happens if there is an excess of one reactant, or if there is not enough of a certain reactant.
Conclusion
PhET Sims are a great resource for students studying chemistry. They offer a way to visualize and better understand complex chemical reactions. The "Reactants, Products, and Leftovers" simulation is just one example of the many simulations available on the PhET website.
