this passage describes a chemical reaction. read the passage. then, follow the instructions below. why are there often holes in slices of bread? the holes are created by bubbles of carbon dioxide gas (co₂) that form in the bread dough before and during baking. these bubbles form when single - celled organisms called yeast break down glucose (c₆h₁₂o₆), a sugar in flour. in addition to carbon dioxide gas, a substance called ethanol (c₂h₆o) forms during this process. complete the table to classify the substances in this chemical reaction. substance reactant product carbon dioxide (co₂) ethanol (c₂h₆o) glucose (c₆h₁₂o₆)
Answer
Explanation:
Step1: Identify reactant - product concept
Reactants are substances that start a chemical reaction, products are what is formed.
Step2: Analyze glucose
Glucose ($C_6H_{12}O_6$) is broken - down by yeast, so it is a reactant.
Step3: Analyze carbon dioxide
Carbon dioxide ($CO_2$) is formed during the process, so it is a product.
Step4: Analyze ethanol
Ethanol ($C_2H_6O$) is also formed during the process, so it is a product.
Answer:
| Substance | Reactant | Product |
|---|---|---|
| carbon dioxide ($CO_2$) | $\checkmark$ | |
| ethanol ($C_2H_6O$) | $\checkmark$ | |
| glucose ($C_6H_{12}O_6$) | $\checkmark$ |
