For this assignment, you will create 3-D models that represent the reactants and products of a chemical reaction. Once your models are built, you will use them to demonstrate and describe the law of conservation of mass. A chemical reaction rearranges atoms by breaking and re-forming chemical bonds. During a chemical reaction, the chemical bonds in a substance are broken and new chemical bonds are formed. The formation of new chemical bonds creates a new substance. This new substance cannot be changed back to the original substance. Chemical equations use chemical symbols and molecular formulas to show what occurs during a chemical reaction. All chemical equations include both reactants and products. Reactants are the chemicals or individual substances that are present before a chemical reaction occurs. Products are the chemicals or individual substances that are present after a chemical reaction occurs. The law of conservation of mass is the natural law that states the same amount of mass is present before and )? Your model should include the correct number of gumdrops for each element in carbon dioxide, consistent use of colors for elements in carbon dioxide, and the correct number and placement of toothpicks (bonds). Did you type one to two paragraphs that describe your models and relate them to the law of conservation of mass? Your document should include the names of the reactants and products in the reaction, the number of molecules that make up the reactants and products, and the type and number of atoms in each molecule of the reactants and products. It should also explain what happens during the chemical reaction and how mass is conserved during the reaction.
Step 7: Revise and submit your project. a) If you were unable to check off all of the requirements on the checklist, go back and make sure that your project is complete. b) When you have completed your project, submit your models to your teacher for grading. Ask your teacher where to put your name on your models. c) Submit your document through Google Classroom assignment!
