this passage describes a chemical reaction. read the passage. then, follow the instructions below. toothpaste contains several chemicals that keep your teeth and gums healthy. one of the most common chemicals in toothpaste is sodium fluoride (naf), which helps prevent cavities. sodium fluoride and water (h₂o) can be made by combining hydrofluoric acid (hf) with sodium hydroxide (naoh). manufacturers then mix the sodium fluoride with other substances, including mint flavoring, to make toothpaste. complete the table to classify the substances in this chemical reaction. substance reactant product hydrofluoric acid (hf) sodium fluoride (naf) sodium hydroxide (naoh) water (h₂o)
Answer
# Brief Explanations:
In a chemical reaction, reactants are substances that undergo a chemical change, and products are the new substances formed. The passage states that hydrofluoric acid (HF) and sodium hydroxide (NaOH) are combined (reactants) to make sodium fluoride (NaF) and water ($\ce{H_{2}O}$) (products).
# Answer:
| Substance | Reactant | Product |
|--|--|--|
| hydrofluoric acid (HF) | ✔️ | |
| sodium fluoride (NaF) | | ✔️ |
| sodium hydroxide (NaOH) | ✔️ | |
| water ($\ce{H_{2}O}$) | | ✔️ |
