Question

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 jellybeans represent sodium atoms, white jellybeans represent hydrogen atoms, black jellybeans represent carbon atoms, and blue jelly beans represent sodium atoms, white jellybeans represent hydrogen atoms, like jellybeans our cruise and carbon atoms, and we jellybeans that is an oxygen atoms.
Identify the number of each jelly bean needed to make both models.

Answer 1

Answer:

Altogether for both models; two red jellybeans, two white jellybeans, two black jellybeans and six blue jellybeans.

Note: Since no specific color was stated for oxygen atoms, the answer assigns blue colored jellybeans to represent oxygen atoms.J

Explanation:

Sodium bicarbonate, NaHCO₃ is a compound composed of one atom of sodium, one atom of hydrogen, one atom of carbon and three atoms of oxygen.

Since red jellybeans represent sodium atoms, white jellybeans represent hydrogen atoms, black jellybeans represent carbon atoms and blue jellybeans represent oxygen atoms, each of the two students will require the following number of each jellybean for their model of sodium carbonate: One red jellybean, one white jellybean, one black jellybean and three blue jellybeans.

Altogether for both models; two red jellybeans, two white jellybeans, two black jellybeans and six blue jellybeans.
