Leann is learning about chemical reactions. She wants to create a model of a chemical reaction, so she is examming the information that she should include. What are the different componets that she should include in her model? A the kinds of atoms that form during reaction B the kinds of molecules involved in the reaction C the kinds of elements that make up a molecule D whether the molecules are products or reactants E whether the products have more mass than the reactants choose three that apply

Explanation:

When modelling the chemical reaction, it is important that the process is explained such that people looking at the model understand what happened in terms of the reactants and products and how they came to be either.

Leann will therefore have to include the kinds of molecules involved in the reaction be they products or reactants. She will also have to include which elements make up the molecules for instance a water molecule would have the elements Hydrogen and Oxygen.

Finally she would have to indicate which molecules are reactant and which are products. Reactants usually stay to the left side of the reaction equation and products stay to the right.
