this passage describes a chemical reaction. read the passage. then, follow the instructions below. aspirin (c9h8o4) is a drug that can be used to relieve pain or prevent heart attacks. aspirin is based on traditional medicines made from the willow tree. people have used these medicines for thousands of years. today, factories make aspirin by mixing salicylic acid (c7h6o3) and acetic anhydride (c4h6o3). when these two substances combine, they form aspirin and acetic acid (c2h4o2). the aspirin is made into pills that are sold as medicine. complete the table to classify the substances in this chemical reaction. substance reactant product acetic acid (c2h4o2) acetic anhydride (c4h6o3) aspirin (c9h8o4) salicylic acid (c7h6o3)
Answer
Explanation:
Step1: Identify reactants and products concept
Reactants are substances that start a chemical - reaction, products are substances that are formed.
Step2: Analyze the reaction description
The passage says salicylic acid ($C_7H_6O_3$) and acetic anhydride ($C_4H_6O_3$) are mixed to form aspirin ($C_9H_8O_4$) and acetic acid ($C_2H_4O_2$).
Step3: Classify substances
Salicylic acid and acetic anhydride are reactants, aspirin and acetic acid are products.
