Question

this passage describes a chemical reaction. read the passage. then, answer the question 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.

in the chemical reaction described in the passage, which of the following are products?
select all that apply.

acetic anhydride (c₄h₆o₃)

acetic acid (c₂h₄o₂)

salicylic acid (c₇h₆o₃)

aspirin (c₉h₈o₄)

Explanation:

In a chemical reaction, reactants are the substances that combine, and products are the substances formed. The passage states that salicylic acid ($\ce{C7H6O3}$) and acetic anhydride ($\ce{C4H6O3}$) are mixed (reactants), and they form aspirin ($\ce{C9H8O4}$) and acetic acid ($\ce{C2H4O2}$) (products). So we identify the products from the options.

Answer:

B. acetic acid ($\ce{C2H4O2}$)
D. aspirin ($\ce{C9H8O4}$)
