question 8 (1 point) for the composition notebook exercise in this lab, you will be writing the procedure for brushing your teeth. for what chemical will you be writing the nfpa chemical diamond in your notebook? co₂ h₂o₂ nahco₃ h₂o question 7 (1 point)

Explanation:

Tooth - paste often contains baking - soda (sodium bicarbonate, $NaHCO_3$). It is a common ingredient in oral - care products for its mild abrasive properties and ability to help with deodorizing and cleaning teeth. The other options ($CO_2$, $H_2O_2$, $H_2O$) are not typical ingredients for which an NFPA chemical diamond would be written in the context of a tooth - brushing procedure. $H_2O_2$ can be in some whitening products but not as common as $NaHCO_3$, $CO_2$ is a gas not directly related to tooth - brushing in this context, and $H_2O$ is a common substance not usually associated with NFPA chemical diamond in this context.

Answer:

C. $NaHCO_3$
