9) Two students are working together to build two models. Both models will represent the molecular structure of sodium bicarbonate, NaHCO3, commonly known as baking soda. The
students are using toothpicks to represent bonds and jelly beans to represent atoms. Red jelly
beans represent sodium atoms (Na), white jelly beans represent hydrogen atoms (H), black jelly
beans represent carbon atoms (C), and blue jelly beans represent oxygen atoms (O).
Identify the number of each color of jelly bean needed to make both models of NaHCO3.
Explain your reasoning.
