Question

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.

Explanation:

Step1: Understand reactants and products

Reactants are substances that start a chemical reaction. Products are substances that are made in the reaction.

Step2: Analyze the reaction description

The passage says "combining hydrofluoric acid (HF) with sodium hydroxide (NaOH)" to make "sodium fluoride (NaF) and water ($H_2O$)". So HF and NaOH are reactants. NaF and $H_2O$ are products.

Answer:

Substance	Reactant	Product
sodium fluoride (NaF)	No	Yes
sodium hydroxide (NaOH)	Yes	No
water ($H_2O$)	No	Yes
