this passage describes a chemical reaction. read the passage. then, follow the instructions below. your body breaks down food by making stomach acid, which is composed mostly of hydrochloric acid (hcl). if your body makes too much stomach acid, you may suffer from an upset stomach. antacids like sodium bicarbonate (nahco3) can relieve an upset stomach by combining with hydrochloric acid. this combination forms sodium chloride (nacl), water (h2o), and carbon dioxide (co2), reducing the amount of acid in the stomach. complete the table to classify the substances in this chemical reaction. substance reactant product carbon dioxide (co2) hydrochloric acid (hcl) sodium bicarbonate (nahco3) sodium chloride (nacl) water (h2o)
Answer
Explanation:
Step1: Identify reactants and products
Reactants are substances that start a chemical - reaction, products are substances formed. The reaction is $\text{HCl}+\text{NaHCO}_3\rightarrow\text{NaCl}+\text{H}_2\text{O}+\text{CO}_2$.
Step2: Classify carbon dioxide
$\text{CO}_2$ is formed in the reaction, so it is a product.
Step3: Classify hydrochloric acid
$\text{HCl}$ is one of the starting substances, so it is a reactant.
Step4: Classify sodium bicarbonate
$\text{NaHCO}_3$ is one of the starting substances, so it is a reactant.
Step5: Classify sodium chloride
$\text{NaCl}$ is formed in the reaction, so it is a product.
Step6: Classify water
$\text{H}_2\text{O}$ is formed in the reaction, so it is a product.
Answer:
| Substance | Reactant | Product |
|---|---|---|
| carbon dioxide ($\text{CO}_2$) | $\checkmark$ | |
| hydrochloric acid ($\text{HCl}$) | $\checkmark$ | |
| sodium bicarbonate ($\text{NaHCO}_3$) | $\checkmark$ | |
| sodium chloride ($\text{NaCl}$) | $\checkmark$ | |
| water ($\text{H}_2\text{O}$) | $\checkmark$ |
