Question

this passage describes a chemical reaction. read the passage. then, answer the question below.
fizzy drinks that come in cans or bottles contain a substance called carbonic acid (h₂co₃). when you open one of these drinks, the carbonic acid breaks down, creating water (h₂o) and carbon dioxide (co₂). this carbon dioxide leaves the drink, forming gas bubbles that you can see rising to the surface of the liquid.
in the chemical reaction described in the passage, which of the following are products? select all that apply.
water (h₂o)
carbon dioxide (co₂)
carbonic acid (h₂co₃)

Explanation:

In a chemical reaction, reactants are the substances that undergo a change, and products are the new substances formed. The passage states that carbonic acid ($\text{H}_2\text{CO}_3$) breaks down. So, carbonic acid is the reactant. The substances created (formed) are water ($\text{H}_2\text{O}$) and carbon dioxide ($\text{CO}_2$), which are the products.

Answer:

water ($\text{H}_2\text{O}$), carbon dioxide ($\text{CO}_2$)
