this passage describes a chemical reaction. read the passage. then, follow the instructions below.
the cheesemaking process sometimes includes a step called lactic acid fermentation. this step occurs when a certain type of bacteria is added to milk. the bacteria form lactic acid (c₃h₆o₃) by combining water (h₂o) and lactose (c₁₂h₂₂o₁₁) in the milk. when lactic acid forms, the milks proteins clump into curds that can later be used to make many types of cheese.
complete the table to classify the substances in this chemical reaction.
| substance | reactant | product |
| --- | --- | --- |
| lactic acid (c₃h₆o₃) | ☐ | ☐ |
| lactose (c₁₂h₂₂o₁₁) | ☐ | ☐ |
| water (h₂o) | ☐ | ☐ |

Question

Accepted Answer

# Explanation:
## Step1: Analyze lactic acid
From the passage, bacteria form lactic acid by combining other substances, so lactic acid is a product.
## Step2: Analyze lactose
The passage says bacteria use lactose (along with water) to form lactic acid, so lactose is a reactant.
## Step3: Analyze water
The passage says bacteria use water (along with lactose) to form lactic acid, so water is a reactant.
