Question
A student tested a sample of carbon (C) by combining it with water. There was no reaction between the carbon and water. The student concluded that carbon must be a group 18 element, since it was unreactive. Is this conclusion correct? Why or why not? (2 points)
Group of answer choices
No. The carbon probably did react, but did not give off any signs or indications of a chemical change.
No. Just because carbon did not react with water, does not mean it wouldn't react with a different compound.
Yes. The student can make a reasonable conclusion based on one experiment.
Yes. Water would react with almost every element, except Group 18 elements.

The correct answer is:
**No. Just because carbon did not react with water, does not mean it wouldn't react with a different compound.**
Explanation: Carbon is a nonmetal and does not react with water under normal conditions, but it can react with a variety of other compounds, such as oxygen (in combustion reactions), acids, and various organic compounds. The conclusion that carbon is a group 18 element based solely on its lack of reaction with water is incorrect, as it does not account for carbon's reactivity with other substances. Group 18 elements (noble gases) are characterized by their lack of reactivity due to their complete valence shell, but not all elements that do not react with water are noble gases.
